When the fluid flows through sensor,impeller rotates under fluid pressure,speed is proportional to mean velocity,impeller rotation changes magnetic

resistance value of magneto-electric converter periodically as following diagram. With it flux in detecting coil changes periodically.Then produce

periodic induced electric potential,called electric pulse signal,after the amplifier amplification,sent to display instrument to show data.2.jpg

water flow measurement feature


· High accuracy,generally ±1%R,±0.5%R

· Good repeatability, short-term repeatability 0.05%~0.2%,available to get high accuracy for regular and online calibration,priority selection in trade settlement.

·  Pulse frequency signal output,available for overall calculation and computer connection  without zero drift,strong anti-interference.

· High frequency signal(3-4kHz),strong signal resolution

· Wide measuring range,medium and large pipe size 1:20 available, small size 1:10

· Compact and light structure,convenient maintain,high flow capacity

· Available for high pressure measurement,no need to dig a whole on instrument shell,made

into high pressure type instrument easily

· Various kinds of sensor type,can be customized per request,ex: low temperature type,

two-way type,underground type etc

· Insertion type,used for large pipeline size measurement,low pressure loss,cheap price,

available to take out without flow cutoff.

explosion proof flow meter application

Turbine flow meter is widely used in petroleum,chemical,metallurgy,organic liquid,inorganic liquid,

liquefied gas,urban gas pipe network,pharmacy,food,paper making industry etc .

Turbine flow meter is used to measure low viscosity,non-corrosive,clean liquid volume and cumulative

flow rate in closed pipeline.
