WHSENSORS electronic liquid level display

The WH311 fire water tank electronic liquid level display is applied to measure the water level of the water tank, with real-time remote display (up to 5 kilometers from a long distance). The WH311 lightning protection water level probe is directly installed at the bottom of the water tank or the water tank, and the WH6 electronic liquid level display is installed in the control room to monitor the real-time water level of the water tank in real time. It also has a high and low liquid level alarm function, which can assist in controlling the water pump to automatically replenish and discharge water, ensuring that the water tank system maintains a high water level and operates normally. The WH311 water level indicator has been specially applied to multiple residential security sites such as Wanda Real Estate and Yaobao Real Estate, effectively solving the problem of liquid level remote measurement and assisting in building digital monitoring.

The WH311 water level gauge adopts an all stainless steel laser sealing structure with a unique triple waterproof design. After 3999 underwater tests, it has an IP68 waterproof rating

Greatly improved the waterproof performance of the product (a geological bureau in Guizhou has used a 1000m deep well without any faults), and the instrument promises to maintain water levels within three years

Replace the probe water inlet bag with a new machine. The Wh311 water level sensor adopts Texas Instruments (TI) company's original chip amplification circuit, greatly improving the sensor signal

Stability of output. Users can extend the water level probe from the fire water tank (pool) site to the control center connection using a 2X1.5 square meter shielded cable on their own

The WH6 liquid level display meter, with a high-performance chip, greatly reduces signal attenuation and can achieve a long-distance transmission distance of up to 5 kilometers.

The WH311 liquid level transmitter is an important application of pressure sensors, which uses the principle of fluid statics to measure water level or liquid level. The highly sensitive silicon pressure resistance sensor made using micro mechanical processing technology is the heart of the liquid level sensor, supplemented by specialized cables with ventilation ducts and specialized water sealing technology, which not only ensures the water sealing of the immersion sensor, but also allows the reference pressure chamber to communicate with the ambient air pressure, thereby obtaining accurate measurement results and excellent stability. The WH311 liquid level transmitter adopts internationally advanced dry ceramic capacitance sensors or isolation diaphragm diffusion silicon pressure sensors with temperature compensation as sensing elements, greatly improving the product's performance. Widely used for water level and liquid level measurement and control in fields such as petroleum, chemical engineering, power plants, urban water supply and drainage, and hydrological exploration.

The WH311 electronic liquid level display is based on the principle that the static pressure of the measured liquid is proportional to the height of the liquid. Using advanced isolated diffused silicon sensors, static pressure is converted into electrical signals, which are then temperature compensated and linearly corrected to standard electrical signals (such as 4-20mA). Equipped with a WH6 secondary display control instrument, real-time water level display and control are achieved.

Control principle - When the water level in the water tank drops to the set lower limit water level value, the liquid level controller sends a command to instruct the pump valve to start water supply. When the water level reaches the set upper limit water level value, the controller sends a command to instruct the pump valve to close and stop water supply. Similarly, if necessary, the liquid level controller can also instruct the water pump or electric valve to perform the opposite operating action.
