Product structure size:

Settlement is a slow process. In any short period, the change reflected in the liquid level of the liquid storage tank will be very small. Whether or not this small change can be detected in real time and accurately, reflecting the small settlement of the foundation, and achieving prevention is the key to measuring the quality of a static level product. This puts forward high requirements for the real-time and precision of the liquid level sensor integrated in the system. As it is installed outdoors, the temperature coefficient, water resistance and lightning protection of the liquid level sensor are key technologies. In addition, the installation dimension and replaceability of the static level gauge are also important technical indicators. It is composed of a high-precision liquid level gauge, a liquid storage tank, a protective cover, a connecting gas and a water pipe.

The differential pressure static level is a kind of precision instrument based on the principle of connecter, which measures the relative changes between the liquid level of several mutually connected liquid tanks installed at the measured point and the liquid level of the liquid tanks at the measurement base point (fixed point), and deduces the settlement changes of the relative positions of the installation positions of each liquid tank.

Precautions for use

! ! !Product power supply 24VDC (range: 9-30vdc);

! ! ! It is strictly prohibited to remove the outer pipe of the product (since it is completely sealed and protected by rubber seal, it is possible to install liquid leakage after removal);

! ! ! The power and signal wires shall be correctly wired according to the specifications of the ordered products;

! ! ! The unused end of the electrical connector must be screwed with a cap;

! ! ! During field installation, the air of the liquid pipe shall be discharged, otherwise the measurement accuracy will be affected;

! ! ! During on-site installation, it is recommended to use metal or plastic pipes for protection of cables and liquid pipes;

! ! ! If there is no liquid in the product, please replenish it in time;

! ! ! Horizontal installation of products;

! ! ! For outdoor installation, it is recommended to install the product in the protective box;
