Insertion type vortex flow meter with 4 - 20 mA high accuracy
Quick Detail:
1. Simple and firm structure, no movability parts, high reliability, apply to long-termed work.
2. Easy to installation and convenient to maintenance
3. Detection sensor not contact the be testing medium directly, stable performance, long life
4. The output pulse signal Proportional to the flow rate, high accuracy
5. Widely measurement range
6. Low pressure lost, low operate charge
Description:
As shown in picture,in the meter body vertical insert a triangular prism root namely the happening of the body,when eddies of medium throught the table body, in triangular prism behind the alternate produce in opposite directions regualr karman swirl,its spiral separation and the flow of the medium frequency F speed by sensing head is proportional to the V detected the number of spiral,can measure the flow velocity,again according to the table body mouth .
