差壓傳訊器
High-accuracy differential pressure measurement.
型號 :
EMIS BAR
The transmitter principle of operation is to measure pressure difference between positive and negative sensor cavities. The device can measure the flow using reducers. Reducer creates the obstacle for the liquid or gas flow. While passing through this section, the flow changes its nature. Negative pressure transmitter measures the difference of pressure before and after the reducer. The bigger the difference is, the higher the flow rate is in the pipe.
