RK-082 Side mounted type differential pressure density meter for automatic measurement instrument of various liquid or liquid mixtures of on-line measurement of the density. Is a kind of instrument for field measurement of liquid density continuous online, can be directly used in the process of industrial production. The intelligent on-line density meter adopts advanced technology, including: a capacitor type high precision differential pressure sensor and a pair of pressure relay which is connected with the production process. A temperature sensor is arranged between the two pressure relays to compensate for the temperature variation of the process fluid. When side mounted type differential pressure density meter is working, the liquid density can be continuously measured online, and the process can be directly used for the control of the production process. Adopting the integrated two wire transmitter structure, no moving parts are easy to install and use, and the maintenance is simple. The belt cleaning device can be cleaned regularly to ensure the accuracy of the use.
二、Operational principle
RK-082 Side mounted type differential pressure density meter is a high precision differential pressure transmitter. Its working principle: liquid column pressure and the fixed height is proportional to the density of liquid.
P=ρgh
In the formula: P——liquid column pressure and the fixed height
ρ——the density of liquid
h——height of liquid column
