high accuracy vortex flow instrument

Brand:aa

Product detail:

 

high accuracy vortex flow instrument

 

Technical Features: 

No moving parts, high reliability and durability

Convenient installation and maintenance

Sensor not contact the measured fluids directly, stable performance and long service life

Output pulse signal is directly proportional to flow rate, high accuracy and no zero drift

Wide measuring range, turndown ratio 10:1

Low pressure loss, low cost

Frequency output not affected by the fluid change in physical character and composition, meter factor (K) only considers shape and dimension of eddies. Measurement of volumetric flow can get compensation once it needs. Then no re-calibration meter factor needed if damaged parts be exchanged

Wide application for steam, gas, liquid

Large temperature range from -200...+400 °C
