Liquid Propane Gas (LPG) Flow Meter – GPI Flow Meter Application

Posted in GPI News by GPI on September 8, 2009

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.

    We do not “officially” have a propane flowmeter but several customers use our G2 Stainless Steel flow meter for propane. These flowmeters are calibrated for water but from what we hear from our customers that calibration works great for liquid propane. I want to stress that the propane must stay in liquid form in order for this meter to work with this type of application.

    Thanks for your questions. The G2S07N09GMA will measure want goes through it at the time it goes through it. It will not compensate for temperature. Hope that helps.

    Can these be used in a condo development where each condo connects to a large LPG tank? Usage will be read monthly and billed per usage. Thanks.

    There are too many times the propane would be flowing below the minimum of the flow meter. The smallest meter I would recommend for liquid propane is a 1/2” meter that reads down to 1 GPM. Pilot lights use a lot less than 1 GPM, so would not be read at all. The answer is no.
