Appropriate Flow meter to measure Diesel for generator

01/03/2022 11:18 PM

Hello Everyone!

Hope you guys would have a great weekend.

My customer want's to measure the daily consumption of Diesel, used by their generators. The diesel enters from the day tank to the generator and the customer wants us to measure the accurate consumption of their diesel. And any communication Modbus TCP/IP or Profibus would be a plus, please suggest any appropriate solution for this.

the line size is 2 inch and flow rate is 50 to 350 l/hr @ 50 deg C max.

You may need two. If there is a return flow line to return excess fuel to the day tank, you will need to subtract that flow from the feed flow.

yes, my client has asked for two nos. of flow meter, I am searching for an accurate and economical solution. we offered them a Coriolis Type flow meter but that was too expensive for the customer.

Level can be easier to measure than flowrate:

  • How about using a dipstick in the day tank every day?
  • How about using change of level in the day tank over time using some level instrument?
  • How about using re-ordering records from the purchasing function over time?
  • etc.

Turbine meter technology was invented for the purpose of high accuracy hydrocarbon fuel flow measurement. Go find some turbine meter vendors.

<...any appropriate solution...>

The original poster claims to be interested in <...daily consumption...>, not necessarily instantaneous flowrate. Consecutive points at intervals on a timeline can do that. See #6⇓.

Invitation declined.

I think what you really want is a totalizing meter (or just meter), rather than a flow meter. Instantaneous flow rate isn't very useful.

Try Googling "fuel meter" instead of "flow meter."

I would suggest that a small Coriolis flow meter be used and provided it has a 4-20mA output you can put it into an analog input card on the PLC.

We had units measuring fuel oil flow which was used on the boiler preheat before changing over to pulverised coal. Very accurate when the unit is sized to suit the flow of the supply.

Keyence makes an inexpensive flow meter up to 2” pipe. It clamps on the pipe. I have used them on gearbox oil flow, 4-20mA output and maybe others available. Worked great. You can integrate the 4-20mA signal and fine calibration using tank levels if necessary.

May be this one is very informative, if you want a Japan made sort of thing. Intrinsically safe sort of things,
