When the TankRadar Rex gauge is connected with a pressure transmitter near the bottom of the tank, the density of the product can be calculated and presented. One or more transmitters with different scalings can be used on the same tank to measure vapor and liquid pressure.

The accuracy of the density calculation largely depends on the accuracy of the pressure transmitter. TankRadar Rex can interface to any pressure transmitter with a standard output of 4-20 mA or HART. The 4-20 mA signal is converted from analog to digital form in the RTG.

The standard pressure transmitter supplied with the TankRadar Rex system for in-liquid mounting is Rosemount 3051S, which has an industry leading performance with 0.025% accuracy.

The 3051S series consists of transmitters and flanges suitable for all kinds of applications, including crude oil tanks, pressurized tanks and tanks with / without floating roofs.

See the Rosemount 3051S web page or Product Data Sheet (00813-0100-4801) for more information.
