Multi-Variable differential pressure transmitter is used for assembling with throttling device such as V-cone, Orifice-plate, Verabar, Nozzle, Venturi etc. to directly display instant flow rate and total flow. Compared with the traditional differential pressure flow transmitter, multi- Variable differential pressure flow transmitter largely 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.
