High precision fire water tank water level sensor

   WH311High level fire water tank water level sensorAccording to the Quality Inspection and Evaluation Regulations for Installation of Building Fire Protection Facilities in China (DB37/242-2008) Standard Trial Version 4.2.2, Article 4The water level of the fire pool should be able to be displayed in the fire control roomWanhe Instrument has developed a real-time liquid level monitoring system specifically designed for the above requirements. The WH311 water level probe is directly installed at the bottom of the fire pool or water tank, and the WH6 liquid level dedicated display is installed in the fire control center to achieve monitoringReal time digital display of fire water level, measurement accuracy can reach (centimeter level), with upper and lower limit alarm control point output, and 4-20mA current output.

WH311High level fire water tank water level sensorHow to install
1. When installing a liquid level transmitter in a stationary deep well or pool, the inner diameter is usually adjusted Φ Fix a steel pipe with a diameter of about 45mm (with several small holes drilled at different heights to facilitate the smooth entry of water into the pipe) in the water, and then place the immersion level transmitter into the steel pipe to use.
2. When measuring the liquid level of flowing or stirred liquids, the inner diameter is usually measured Φ A steel pipe with a diameter of about 45mm (several small holes are drilled at different heights on the opposite side of the liquid flow direction),
To facilitate the smooth entry of water into the pipe, fix it in the water and then place the immersion level transmitter into the steel pipe for use.
3. The installation direction of the transmitter is vertical, and the installation position of the input type should be away from the liquid inlet and outlet and the mixer.
4. In situations where there is significant vibration, steel wires can be wrapped around the transmitter to reduce vibration and prevent cable breakage

WH311High level fire water tank water level sensorPrecautions for use
1. If any abnormalities are found during use, the power should be turned off, the use should be stopped, and an inspection should be conducted or the technical department should be contacted
2. When connecting to the power supply, it is necessary to strictly follow the wiring instructions of the Wanhe instrument.
3. When transporting and storing the liquid level transmitter, the original packaging should be restored and stored in a cool, dry, and ventilated warehouse.

WH311High level fire water tank water level sensorControl requirements

To pass the fire inspection, a fire pool or water tank must have a fire product qualification, a product qualification certificate, and a complete set of fire inspection documents.
*One of the important provisions of the fire protection standards for buildings is that a liquid level display controller that can see the water level of the fire pool or water tank must be installed in the fire control center or security room.
*The WH311 fire acceptance dedicated water level display controller not only allows you to see the water level of the fire pool in real-time in the fire control room, but also upgrades and replaces the previous generation of high-precision float level measurement, and achieves high and low water level alarm and automatic water pump replenishment and drainage.

The WH311 fire pool water level display device of Dongfang Wanhe Instrument can be installed and set up without professional personnel. The installation method of the input type is simple and convenient, and the distance from the liquid level sensor (probe) to the display instrument can reach 4000 meters for remote control display. It has real-time digital display, measurement accuracy can reach (centimeter level), upper and lower limit alarm control point output, and 4-20mA current output. It is an updated product of traditional floating ball and electrode water level gauges.
