Multivariable Differential Pressure Flow Transmitter

MultiVariable transmitter is generally used together with differential pressure flow device such as V-cone, Orifice-plate, Verabar, Nozzle, Venturi etc. to directly display instant flow and total flow. Compared with the traditional differential pressure flow transmitter, multi-Variable differential pressure flow transmitter greatly reduces the cost of installation and after-sales maintenance. Multi-Variable differential pressure flow transmitter is widely used in petroleum, chemical, electric power, metallurgy, shipbuilding, Pharmacy, textile, papermaking and environmental protection industries.
