Chuanyi Differential Pressure Flowmeter Technical Data and Selection Guide
مقياس تدفق الضغط التفاضلي Chuanyi is supplied by SANTAN for industrial process control, pipeline instrumentation and maintenance replacement projects.
ملخص المنتج
Chuanyi differential-pressure flow measurement solutions determine flow from the pressure difference generated by a primary flow element. The system normally combines an orifice, nozzle, Venturi or averaging element with a differential-pressure transmitter, manifold, impulse piping and pressure-temperature compensation where required.
Chuanyi Product-Family Information
Chuanyi lists differential-pressure flowmeters as part of its complete flow-instrument portfolio for gases, liquids and steam. The measurement system must be engineered as a complete assembly because primary-element geometry, line conditions, transmitter range and installation directly affect uncertainty and pressure loss.
