Purpose:
LED-1151DP type △ P flow transmitter is specifically designed to receive differential pressure signals from throttling elements, which are converted into 4-20mA.DC signals proportional to the flow rate through a "J" type electronic circuit board with square root function.
This product uses electronic switch components to switch the relationship between the output current below 20% and the input differential pressure to linear, reducing the instability of the output current of the flow transmitter in the initial working section (especially at zero). However, when the output current is below 50%, due to the higher conversion sensitivity of the flow transmitter compared to differential pressure transmitters of the same specification, its stability is still slightly inferior to differential pressure transmitters.

The applicable range of the technical data in the table is: output square root current 20-100%. 2. The accuracy between output current 20-50% is 0.2 level × 50%/output current (%). 3. Additional errors caused by static pressure and temperature are measured at the maximum range.
