What is gravity feed flow meter?

Gravity feed flow meter means a kind of flow meter can run via gravity feed system without pump to push more pressure to run the fluids. This kind of flow measurement can be a little difficult and tough job, because the flow rate and flow velocity is small, and the fluid is not full of pipeline, not all flow meters can detect the low flow at low pressure condition. However oval gear flow meter is a kind of gravity feed flow meter , but this kind of flow meter still needs the liquid fill the pipeline when measuring the flow rate, also the liquid could run ( not static) on the pipeline with the only help of gravity feed system.

How gravity feed flow meters work?

Gravity feed flow meter uses mechanical measuring elements to continuously divide the liquid into a single known volume part, and measures the total flow volume according to the number of times that the metering chamber is filled and discharged with the volume part of the liquid successively and repeatedly.

Gravity feed flow meters applications

Gravity feed flow meters can work on below liquid applications; it can measure below liquid flow rate and total flow:
Heavy oil, polyvinyl alcohol, resin, crude oil, diesel, gasoline, kerosene, light oil, asphalt, lubricating oil, vegetable oil, petroleum, residual oil, motor oil, fuel oil ,heat transfer oil, hydraulic oil, syrup, water . The liquid should be clean without any solids or particles.

Features of gravity feed flow meter

  • High accuracy gravity flow meter with accuracy from 0.5% to 0.2%;
  • Gravity feed flow meter is a kind of perfect performance on high viscosity liquid flow measurement;
  • Gravity feed flow meter can be a direct-reading flow meter without any power supply.
  • Gravity feed flow meter can be made into digital flow meter with electronic reading display , pulse output , 4-20mA output, HART and Modbus RTU.
  • Low pressure loss
  • Low price cost flow meter price starts from 150 $
