Liquid Turbine Flow Meter

Liquid turbine flow meter is a kind of precision flow measurement instrument. It can be used to measure the flow rate and total amount of liquid together with the corresponding flow calculation instrument. ATO provides liquid turbine flow meter with optional 4-20 mA signal output, RS485 also available. Liquid turbine meters often used in petroleum, chemical and other industries. Both wholesale and bulk, ATO will be the most cost-effective choice in China.

Liquid turbine flow meter


  1. Compact and light structure, easy installation and maintenance, large circulation capacity.
  2. High accuracy, generally up to ±1%R, ±0.5%R, high precision up to ±0.2%R. Magnetic flow meter also provides accurate detection
  3. With three point correction of instrument coefficient, intelligent compensation for nonlinearity of instrument coefficient, and can be corrected on site.
  4. This type of flow meters suitable for high pressure measurement, the instrument body does not need to open the hole, easy to make high pressure instrument.
