Diesel Fuel Saving Flow Meters for Work Boats
Flow Meter Application:
Determining fuel used for generating power on work boats reduces the amount of taxes owed. Additionally, accurate data about motor performance can pinpoint efficiency problems resulting in fuel savings. When fuel prices soar this cost savings increases, creating a demand for an accurate system to determine “net use.” The GPI GM005 meter combined with the GX500 provides a “green” solution for reducing fuel used in work boats.
Flow Meter Problem:
Fuel use on work boats determines the tax paid on fuel. Fuel used for generating power is not taxed. Until recently,boat captains had no way to accurately determine the amount of fuel used for generating power. Estimating this difference often resulted in overpayment of taxes. Determining accurate net use, helps compare efficiency between boat engines. Adjustments can then result in additional fuel savings.
Company Type: Work Boat Fleet Operator
Market: Transportation
Application Category: Efficiency Improvment
GPI Flow Meter Used: GM005A2H41-6

Flow Meter Solution:
GPI’s GM005 combined with the GX500 provides an accurate way to measure net use. One GM005 and GX500 is installed on the supply line with a second pair installed on the return line. This system allows an operator to compare fuel consumption versus speed and achieve the most efficient use of fuel. Reducing fuel costs, tax relief and “green” benefits result by using the GPI “net use” method.

Micro-Brewery and Wine Flow Meters:Flow Meters for Beer Making
Micro-Brewery and Wine Flow Meters
As with any beverage making process, consistency and control are the keys to quality product. GPI offers a variety of meters to help you ensure a consistent brew. All meters provide totalizing (or volume of liquid) and flow rate (or speed of flow), two features not commonly found in a single meter. Using the totalizing feature allows you to accurately control the amount of water used in the mashing process to obtain the correct ratio of water to grain. These meters display an instantaneous flow rate of the hot water being added. You can reduce or increase the flow rate to obtain the correct water temperature for every batch. In the sparging process, the meter will not only allow you to visually verify your flow rate but will also show exactly how much water was used. The meter will pay for itself in short order just by using it in the tank cleaning process. By showing you how much water was used, you will know how much chemical is required for the proper concentration and stop wasting expensive cleaning solutions.
Whether you are looking for flow rate or total volume, one of the GPI meters will ensure batch to batch consistency and help reduce cleaning and maintenance costs.
GPI has three flow meter families to address brewing’s unique requirements:

Liquid Propane Gas (LPG) Flow Meter – GPI Flow Meter Application
Flow Meter Application:
Service stations and other fuel outlets sell propane via a traditional retail dispenser and also using a secondary line to fill portable LPG bottles. Selling propane in portable LPG bottles requires measurement by weight as opposed to volume. Customers require a simple, accurate way to capture total dispensed propane to control inventory. Reconciling records and inventory can take time and the confidence in accuracy is often a concern.
Flow Meter Problem:
Stations need a way to monitor propane dispensed by volume and by weight for inventory tracking. The propane dispenser uses volume measurement while portable bottles are sold by weight. The solution to track both amounts requires accuracy, simplicity and must be economical. This application requires reliable measurement with easy maintenance.
Company Type: Propane (LPG) Marketer
Market: Oil and Gas
Application Category: Inventory Management
GPI Flow Meter Used: G2S07N09GMA

Water Flow Meter Exclusive:Interview With The New TM Series Water Flow Meter (Yes! The Actual Flow Meter)
The following interview took place at the GPI Flow Meters Media Center the day before the new TM Series Water Flow Meter was released. This interview included other celebrity types like the Industrial Grade Flow Meters, Positive Displacement/Oval Gear flow meters and a few other crowd pleasers from the GPI Industrial flow meter family.
Note: This interview is an exclusive to The Official GPI Flow Meters Blog

TM displayed on a billboard on Water Measurement Boulevard
It has been several years now that people around the world have enjoyed the reliability of our blog guest today. The TM Series water flow meter has been re-engineered and is looking better than ever. Today we have “TM” with us and he is going to tell us what he and his flow meter entourage have been doing over the last year. We hope you enjoy this interview and in the process learn more about these types of economical water flow meters.
GPI Flow Meter Blog:
Good day TM, I couldn’t help but notice your arrival to the studio. Do you usually travel with this many water meters? It seems as if you have a lot of family with you.
TM Water Flow Meter:
I work solo most of the time. However, sometimes I get to work with a lot of my family because it takes more than one of us to do the job right. Just ask any sub-metering plant manager. They love us everywhere we go. If we were a rock band they would be our groupies.
GPI Flow Meter Blog:
Ha Ha! That is great that you feel that way about sub-metering plant managers. Recently, I ran across a flow process control paparazzi Web site that had some pictures of you on vacation. That is rare for your kind. It seems that you are always working.

A blurry picture taken by a paparazzi of the TM while on vacation after 9,000 hours of continous work.
TM Water Flow Meter:
I do look nice and tan in that picture that is for sure. As you can tell my color has changed because of that vacation. Who knew that applying tanning lotion instead of sun block would make you look gray? Those pictures were taken without my consent but “it is what it is.”
I decided to take a vacation because I had to get new batteries in me. You know I worked for about 9,000 hours straight on two lithium batteries. I needed to get away for a bit. It is always nice to get new batteries after all that intense labor.
GPI Flow Meter Blog:
Wow! That does call for a nice vacation. I want to ask you some questions that we received through Twitter. Here is a question from one of our readers.” I researched water flow meters and I found you but in your white PVC incarnation, has your body changed? Are you the same great meter?” That question came from @davidengineer, a water treatment systems engineer.
TM Water Flow Meter:
David, my man, lucky for you I have been pumping some iron, saying my prayers, and taking my vitamins, as the great Hulk Hogan once said. I have been working out in the gym for about six months and I now meet schedule 80 specifications. I have bulked up. I can now sustain pressures of up to 225 PSIG. I know you water treatment engineers like the schedule 80 so while I was in the gym I had a picture on the mirror of one of you. This helped me focus so that someday I could work hard for you. I am here to let you know that I am ready for action.

Spigot Model TM Series Water Meters can be used with different glue-on fittings, male or female. SMILE!
GPI Flow Meter Blog:
You have been upgraded from schedule 40 specifications to meeting schedule 80 specifications; that is really great because that makes you tougher. A lot of questions also came from Facebook and one that seems to come up a lot was the type of fittings that you work well with. Can you give us some information on that?
TM Water Flow Meter:
Yeah, I can inform my fans out there (or soon to be fans) that I can start working for you with any type of fitting imaginable. You can buy me with a spigot fitting or a female NPT fitting. However, if you order me in a spigot model you can go to a hardware store or your local plumbing supply store and buy any type of fitting you want to use and glue it to both of my ends. This means I can mingle with flange fittings, union fittings, couplers, or any other threaded fitting, male or female.
I hope this doesn’t sound pretentious but can I brag a little about my family. I am the big dude in our family of water meters, 2″, but other members include ½”, ¾”, 1″, 1 ½”. You can buy one of us or all of us; we can work alone or in a group and will work hard for you.
GPI Flow Meter Blog:
Do you all vary in how many gallons or litres per minute you can measure because of the difference of size?
TM Water Flow Meter:
Yes, we are all hard workers but we have our limits when it comes to running water through us. Below is a picture of our latest specification that includes our model, size flow rate abilities. This picture was published in a snazzy flow meter magazine. I liked the editor of the magazine a lot. He took me to a fancy restaurant where they used nothing but Fiji water; you know that fancy tap water that comes in a square looking bottle and is sold for more than the others. He had tea and some type of sweet bread.
GPI Flow Meter Blog:
I can’t help but notice that your display decal is a different color, blue looks good on you.
TM Water Flow Meter:
My distant relatives like the G2 Series flow meters have had blue decals for a long time. I decided that I needed to step up my game so I went ahead and made the change. If you are out there looking for me all you have to do is “LOOK FOR THE BLUE LABEL!” and I am sure you will find me or one of my compadres.
GPI Flow Meter Blog:
TM you are internationally used and known. I wanted to clear up some confusion on the types of readings and information you show on your display. However, I feel like you know more on this matter than I do, can you explain this to our readers?

A Breakdown on what the TM Water Flow Meters Read on their Display
TM Water Flow Meter:
It is simple, my man, I can read rate of flow and total, which is both batch and cumulative.
Let me break this down for you, my cumulative totals are just like your odometer in your car, you can not reset them but it keeps track of everything that has gone through me.
My batch total is like your trip odometer, you can reset it once you are done measuring for your application. I know some of the people I have worked with in the past enjoy this feature of mine because they can reset me at the end of their work day to see how much work I did for them that day.
However, I can also give you the flow rate just like your speedometer in your car. If you press the gas pedal in your car your speedometer tells you how fast you are going. Well if you run water with a certain amount of pressure I can tell you how many gallons per minute are flowing through me at that very instant.
For my metric peoples I also read in litres per minute. I want to take this time to shout out to my good buddies in Canada, I will be working for you all soon, eh! (Also long live Bret “The Hitman” Hart and the Hart Foundation)
GPI Flow Meter Blog:
We are running out of time but we have a couple of more questions for you that came to us through e-mail. Here is the first one: “I am a manager and I usually am not close to where my water meter is installed, it is a pain for me to have to walk all the way to where I have it installed, can you be remotely installed? Can I get you with a remote kit so that I can just sit in my comfy chair and see what you are metering for me?”
TM Water Flow Meter:
Definitely! You can add the standard remote kit and have my display about 100 feet away give or take a few feet. I know some of you don’t think you want my display in your office and I am cool with that. If you decide you want me to give you the latest and greatest at a convenient location you can always add this remote kit down the line. No biggie.
GPI Flow Meter Blog:
TM what about if someone doesn’t want a display and they just want to be able to get you to send them pulses so that they can be viewed in their Programmable Logic Controller (PLC)?
TM Water Flow Meter:
That is easy! All they need to do is buy one of my cousins like the TM200-P or any other cousin with the last letter being a P. They will then be able to get pulses to go straight to their PLC and make their life a lot easier.
GPI Flow Meter Blog:
And the final question that came from our online readers is,”I see your display is on horizontally but my pipe is installed vertically. It is difficult to read the display unless I turn my head 90 degrees. Can I modify your display so that I can see what you are displaying easier?”

TM Spigot Water Meter with 90 Degree Adapter
TM Water Flow Meter:
Oh, don’t turn your head, that’s uncomfortable and might cause a cramp in your neck. Just modify the display by having me team up with the 90 degree kit. He and I go way back! He allows me to be installed vertically but gives me the flexibility to show my display horizontally. This makes it easier for you to read my display and it will save you a trip to the chiropractor.
GPI Flow Meter Blog:
TM we want to thank you for granting us this exclusive interview. Our blog readers will enjoy reading about all you have to offer in your upgraded version.

TM Water Meter Then and Now Comparison
TM Water Flow Meter:
