Application 2: Biogas Flow Measurement

Inquiry Content

Hi, we need a suitable flow meter for below application:

Application =  biogas.65-70% methane, 30-35% CO2. We are assuming average gas flow of 5m³per day. Max flow would be 15m³/day. Approx 10 litres/min.

Currently using an inch line. Temp of gas is ambient. 20 degrees Celsius. Pressure can be between 3kpa gauge and zero gauge. And the biogas is not dry , it is wet and contained around 8% water.  I need temperature and pressure compensation as well please .

I was thinking of your Cone flow meter.  That can handle the wet biogas.

Answer to the Inquiry

Hi, after checking your case, we think the pressure is too low. Your pressure is really low , and V-cone flow meter has large pressure loss. for the little pressure , the biogas can not pass the  flow meter.also one inch size v-cone flow meter is really too small, and can not calibrate in the factory,

But we recommend our thermal mass flow meters. The best part for this gas flow meter is that it can work for your low pressure operation , and it does not need any temperature and pressure compensation, it can display normal flow (Nm3/h). if the water content is not more than 15%,our thermal mass flow meter can also work. See below proper type thermal mass flow meter..

  • SRK-100-25-I-PL-F-16-6-A1-T0-P1-D-1-A0-E
  • SRK-100 seires thermal mass flow meter
  • 25-Gas Flow meter size : one inch
  • I-Transmitter compact type.
  • PLF-Process connection: Flange connection
  • 16-Probe diameter 16mm
  • 6-Probe material 316 stainless steel
  • A1-Explosion proof : with
  • T0-Operation temperature: -20~60
  • P1-Operation pressure:0-1Mpa
  • D-Power supply:24V DC
  • 1-Output:4-20mA
  • A0-No alarm request
  • E- With digital display.
