Differential Pressure transmitters from Fuji Electric

Differential pressure transmitters can be used to measure, flow, density, viscosity and level.

Flow measurement, DP transmitters measure the pressure drop accross orifice plates, venturi tubes, pitot tubes or some other form of primary flow element. In these applications there is a square law relationship between the differential pressure and the flowrate. When specifying a dP transmitter for a flow applications the type of fluid, line pressure and temperature as well as flow trundown should be known.

Fuji Electric have recently released the worlds first DP transmitter which will measure differential pressure at line pressures up to 1035 barg!. This "high static pressure" device is particulary useful in the oil and gas industry as producers drill to new depths to recover product.

Density Measurement, DP transmitters measure the difference in pressure between two points in a vertical plane. The density being proportional to the difference in pressure.

Viscosity Measurement, in this application a fixed flowrate is pumped through an orifice plate at a constant rate using a positive displacement pump at a known telperature and pressure. By measuring the differential pressure accross the orifice plate, the viscosity of the fluid can be measured.

Level Measurement, in this application the level in a sealed tank can be measured by comparing the pressure at the top of the tank, with the pressure at (or near) the bottom of the tank. fuji Electric DP transmitters have the capability to compensate for tanks with irregular shapes.
