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
According to the pressure measuring pressure value in measuring acceleration of gravity with known height of liquid column under the condition, can be measured liquid density.
