The WDP3851, developed by the research and development Engineers of "A.Yite Group", is specially applied to the differential pressure and flow measurement in HVAC field and Environmental Water Treatment field. It could be used to monitor the differential pressure in the heat exchanger of water chiller unit, by-pass system of differential pressure and the differential pressure in pump and filter, and mainly to measure the differential pressure in automatic buffered filter in Environmental Water Treatment field

The WDP3851 differential pressure transducer adopts capacitive sensor which is the most widely applied with mature technology, and "A.yite Company" provides three type against special customers' requirements, N type (Normal Simulate type), G type (General Intelligent type) and S type (Standard Intelligent type). The intelligent series products could be reset to zero or recalibrated the measurement range in the field by local button through manual operator or communication software to realize the passive calibration and date configuration.
　

Application:

1. Differential pressure and flow measurement:

To measure the differential pressure and flow in the heat exchanger of water chiller unit and the range out of the water chiller unit.

2. Flow measurement:

Together with orifice plate, to provide accurate flow measurement and control.

3. Differential pressure measurement:

To measure the differential pressure in the I/O ports of automatic filter in order to decide whether to back flush or not.

4. Fluid level control:

To measure the pressure and fluid levels of storage tank and pressure container
