Abstract
A slurry differential pressure density meter comprises a vertical measuring pipeline, a differential pressure transmitter and a DCS (Distributed Control System). The slurry differential pressure density meter is characterized in that upper and lower sampling points for measuring the medium pressure are arranged on the vertical measuring pipeline; pressure sensors are arranged at the two pressure sampling points and are connected with the differential pressure transmitter; a pneumatic switch valve is mounted at the lower part of the vertical measuring pipeline; and electrical signals of the differential pressure transmitter and the pneumatic switch valve are connected with the DCS. According to the slurry differential density meter disclosed by the utility model, the density is measured by a method of measuring the differential pressure; proved by actual use, a preset purpose is achieved; and the slurry differential pressure density meter can be widely applied to the measurement of slurry density and is especially used for detecting the slurry density of phosphate fertilizer enterprises.
Description
Technical field
The utility model relates to instrument and meter and monitoring management system, particularly relates to
A kind of differential density meter
Background technology
The phosphorous chemical industry enterprise particularly pulp density of phosphatic fertilizer company is difficult to detect, and big multimedium has particle, has burn into that factors such as medium instability are arranged, so the density of medium measurement data is unstable, the fluctuation big.Prior art is measured with methods such as nuclear density gauges; Receive the influence of medium, tube wall often fouling occurs and need often demarcate and verification, and the used radioactive source of nuclear density gauge has injury to human body; Maintainer and operating personnel are had fear at heart, very big environmental issue is arranged.
Summary of the invention
The purpose of the utility model provides a kind of differential density meter, to overcome the deficiency of prior art, satisfies the Density Detection of various slip liquid.
To achieve these goals, the technical scheme of the utility model is following:
A kind of slip differential density meter comprises vertical measuring channel, differential pressure transmitter and DCS control system, its
Be characterised in that said vertical measuring channel is provided with the sampling spot of two measuring media pressure up and down; Two pressure samples points have pressure transducer to be connected with differential pressure transmitter; Vertically a pneumatic on-off valve is installed in the measuring channel bottom, and the electric signal of differential pressure transmitter and pneumatic on-off valve links to each other with the DCS control system.
Differential pressure transmitter and pressure transducer are divided into malleation side and suction side; Calibrated altitude is H between two pressure samples points; Vertically a pneumatic on-off valve is installed in the measuring channel bottom, and the signal of differential pressure transmitter and pneumatic on-off valve links to each other with the DCS control system, realizes the computing of density and the control of valve at DCS; The utility model is through measuring the method density measurement of differential pressure; Control slip liquid short-term in vertical measuring channel automatically periodically and stop to flow, vertically become liquid differential pressure static, steady state (SS) in the measuring channel, according to static pressure formula ρ=P/Hg bulk density; Guaranteed that the differential pressure P that records is the pressure reduction that the physical action by slurries height difference H, fluid density ρ, gravity acceleration g forms; Being density changes with the variation of differential pressure, has got rid of flow velocity dexterously to tonometric influence, has scientifically guaranteed the accuracy that pulp density is measured.The error link that this device produces is few, and equipment dependability is high, has good practical value, is worth applying in industry spot.
The utility model has reached predetermined purpose through the actual proof of using, and it can be widely used in pulp density and measure the particularly detection of the pulp density of phosphatic fertilizer company.
