The insertion-type differential pressure density meter can be installed on the top or side of the tank. The differential pressure digital density meter uses the differential pressure principle to calculate the density value based on the differential pressure value of the medium at a certain vertical distance. It automatically compensates, offering high accuracy, good reliability, and simple installation and use.
The online density meter generates a corresponding 4-20mA signal based on the concentration and density, allowing for remote calibration and monitoring via digital communication. Intelligent differential pressure density meters are widely used in industries such as food and petrochemicals.

Installation
- The product must be inserted vertically from the top, as shown in the installation diagram; the perpendicularity to the ground should not exceed 5 degrees. If the installation is not vertical, or if the local gravitational acceleration deviates from the standard gravitational acceleration, deviations will occur. How to eliminate these deviations will be explained later.
- When installing from the side, ensure the straight section of the flange can be easily inserted.
- After opening the cover of the electrical box, tighten it during reinstallation to ensure tight contact with the sealing O-ring. If not tightened, moisture will enter the electrical box, affecting the normal operation of the circuit.
- The densitometer casing must be effectively grounded.
- The installation location should be as far away as possible from frequency converters or high-power motors. If necessary, take isolation measures and use a shielded power cord.
- After installation, zero the tank when empty, so that the density value displays 0 g/cm³.
