Product Description

This dp cell transmitter is used to determine the quantity of liquid inside a pressurised tank by measuring the difference in pressure between the bottom and top of the tank. Measuring the differential pressure removes the component of gas pressure at the top of the tank leaving the hydrostatic pressure generated by the liquid column. The hydrostatic pressure can then be converted into a liquid height and incorporated into the volume calculation for the storage tank.

The DPT200 dp cell transmitter is a robust heavy duty pressure measurement instrument with a high and low pressure connection port to allow two pressure inputs. The DPT200 will measure the pressure difference between the Hi & Lo side and will output the result as a 2 wire 4 to 20 milliamp current loop signal.

Pressurised tanks are used to store liquids which would otherwise easily evaporate or return to a gaseous state because of vaporisation and boiling. These storage tanks are located on sites which have adopted process industry standards such as HART communications, mounting flange connections, armoured cable termination, and controlled by regulatory standards such as ATEX intrinsic safety or flameproof certification for flammable risk environments.
