Flowmeter for Kerosene Dilutant in Oil Extraction Application
Flow Meter Application:
Measure the Kerosene Dilutant (KD) pumped into the earth to breakdown the gravity composition of crude oil. This process helps extract crude oil from oil wells for processing. Monitoring the amount of KD pumped, results in accurate cost for each oil well. After installing the GM002 with Standard Display, the user realized a cost savings and had an accurate count of KD used.
Flow Meter Problem:
The user needed a way to monitor the amount of Kerosene Dilutant pumped into the earth during the process of extracting crude oil. The cost of this product ranges from $80 – $100 per barrel so using unnecessary dilutant can drive up the cost of extracting the crude oil. An accurate, easy and cost-effective meter was required to solve the problem.
Company Type: Chemical Mixing
Market: Mining
Application Category: Monitoring
GPI Flow Meter Used: GM002S2C41-5
Flow Meter Drawing:
Flow Meter Solution:
Tank holds 1,000 barrels of KD with various lines coming out to feed multiple oil site locations. Place the meter before the pump and above ground at the oil well site. The pump mixes the KD fluid and transports it through rods into the earth. After the crude is broken down, another pump at the bottom of the well, pumps the crude above ground.

GPI Flow Meter LCD Display Explained

If you are familiar with our GPI flow meter brand you probably know or have experience with our electronic digital flow meter display. We believe that our flow meter display is one of the better ones out on the market today. In this post we will explore what we call the “new” GPI 9 LCD electronic display that is being shipped with our TM Series Water Meters, G2 Series Industrial Grade Flow Meters and our A1 Series Flow Meters. We hope that by the end of this post you will be familiar with some of the basics of this flow meter display and have a better understanding on how it works with our flow meters.
What does the “new” GPI 9 flowmeter display do?
Allows you to measure batch & cumulative flow totals
The GPI 9 flowmeter electronic display gives you two totals, one for batching a set amount of liquid that you can reset and the other is a cumulative total that can’t be reset. An easy way to understand these two totals is if you think of the batch total as your trip meter in your car. The trip meter allows you to see how many miles you have traveled with the ability to reset it whenever you see fit. That is the same thing the batch total option on this flowmeter display does, it allows you to measure an amount of liquid with the ability to reset it at anytime. The way to remember how the cumulative total works is if you think of your car’s odometer. The odometer measures how many miles the car has traveled but you can’t reset it. The cumulative total option on this display measures the same way as the odometer, total gallons or litres that the meter has measured in its lifetime use.
Measures Flow Rate
The GPI 9 flow meter display allows you to measure the flow rate of liquid being measured. The flow rate is typically measured in gallons or litres per minute (GPM or LPM). This new display allows you to measure in units per minute, units per hour and units per day. If you need to measure how much water your applications has running through it per hour all you have to do is hit a couple of buttons and the display will change from measuring gallons per minute to gallons per hour. The flow rate is like your speedometer in your car, it tells you the speed that your liquid is traveling through your line or application. This feature is good if you are monitoring how fast or slow your liquid passes through your pipes.
Non-Volatile Totals = No Data Loss
If you have ever used one of these displays in the past you would have noticed that when you replaced your batteries the totals zeroed out. In this new configuration of the GPI 9 display, when you change your batteries your totals will still be available once the meter is powered back on. This is also a great feature if you install your flow meter in a remote area that you only check on every now and then. If the meter display happens to lose battery power by the time you get a chance to check it, you can rest assured that once you put new batteries on the display your totals will still be available for you to see.
5 Year Battery Life = Display Doesn’t Turn Off
If you have purchased one of these new displays you might have noticed that the display never shuts off. The main reason that this happens is because of the Lithium battery life of five-years. We used to send flow meters that had this display with a battery tab installed that needed to be pulled in order for the display to turn on. This display has a five year battery life regardless of whether it is on or off. The power that this display draws is very small therefore it affords for a long lasting battery life.
Easy-To-Use Correction Factor Method
The new display allows you to calibrate your meter by inputting the plus/minus correction factor. You may want to custom calibrate the meter after testing using your actual fluid conditions. You can field calibrate the meter by using the buttons to enter the percent of change you want the display to correct. Values from -99.99% to +99.99% can be entered.
Various Factory Calibration Units Available
This flow meter display’s standard factory calibration is in gallons and litres. However, the display can be configured to read in imperial gallons, quarts, ounces, cubic feet, cubic centimeters, cubic meters or barrels.
Ability to Count Past 999,999
In past versions of this display you were only able to read flow rates up to 999,999 because of the six-digit allowance on the display. This new flow meter display will illuminate a X10 on the top right once you have gone past 999,999. This gives you the ability to know that you are at 1,000,000 and above. If you go past 999,999 X10 then the meter will go back to 100,000 and a X100 will be illuminated on the top right corner instead of X10.
What are the differences between this flow meter display and the previous version?
- Gallons read GL instead of GAL.
- Litres read LT instead of LTR.
- Flow Rate displays as FLOWRATE/M instead of FLOWRATE. The M at the end of FLOWRATE means gallons or litres per minute depending on how you have the display set to reading. This can also be switched to read FLOWRATE/H to measure per hour or FLOWRATE/D to measure per day, with the exception of the TM series meters.
- Top right side of the meter reads FAC instead of PRESET. If these three letters are showing it means that the display is being used under the factory calibration. If you custom calibrate it for your specific liquid the FAC will not show. This will help you know in what calibration mode you are under.
- TOTAL 1 doesn’t say locked but know that this is the cumulative total and you can’t zero it out.
- TOTAL 2 says BATCH next to it indicating that this is the total you should be on if you want to run batches at a time.
- The numbers are wider therefore making it easier to read.
- The display will not shut-off.

Water Meter Applications
Customers tell us they use GPI meters in water processing and irrigation applications. Examples include: make up water, rinse or feedwater and monitoring of greywater. Greywater alone can be used in irrigation districts, landscaping, golf courses, parks and any industry that uses non-potable water.
HVAC Cooling towers and boilers found in large buildings provide another application. These systems use large amounts of water so efficiency and waste can be a real problem. GPI meters can help solve this problem by monitoring flow rates and water usage. Think of building design sites, cold storage or medical equipment facilities, manufacturing plants and other similar industries.
Reverse Osmosis sites frequently use meters with water. GPI Meters can measure water on the inlet and outlet of large R.O. and chemical feed systems. GPI Meters offer a substantial cost savings when compared to mag meters.

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 Drawing:

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:
