Dam water level monitor, integrated detection of liquid level and temperature

Overview of WH311 Dam Water Level Monitor with Wanhe Instrument and Integrated Detection of Liquid Level and Temperature:

oneThe WH311 liquid level gauge uses a stainless steel isolation diaphragm as a signal measuring element, and has been automatically tested by a computer. The zero point and sensitivity temperature compensation in a wide temperature range have been achieved using laser resistance adjustment technology. The amplifying circuit is located inside a stainless steel casing, converting the sensor signal into a standard output signal, fully leveraging the technological advantages of the sensor and giving WH311 excellent performance. It is anti-interference, with small temperature drift, high stability, and high measurement accuracy, making it an ideal liquid level measurement instrument in the field of industrial automation. The measured medium can be water, oil, acid, alkali, industrial sewage and other conductive and non-conductive liquids, and can overcome the influence of false liquid level caused by liquid foam.


The WH311 circuit of the dam water level monitor and integrated liquid level and temperature detection WH311 adopts the original chip amplification circuit of Texas Instruments (TI) in the United States, greatly improving the stability of the sensor signal output. The high-performance chip greatly reduces signal attenuation, and users can use 2 * 1.5 square shielded cable to extend the distance between the display meter and water level probe, and the remote transmission distance can reach 5 kilometers.

Then the display will have two relay switch outputs, which will automatically alarm at low and high positions (this value can be set by the user according to the process).

Dongfang Wanhe WH311 Dam Water Level Monitor, Integrated Detection of Liquid Level and Temperature
Dam water level monitor, integrated detection of liquid level and temperatureIt is an important means to grasp the patterns of groundwater changes, understand the status of groundwater exploitation, and guide the protection of groundwater resources. The groundwater monitoring system can conduct long-term monitoring of parameters such as water level, temperature, and quality of groundwater, and automatically store monitoring data. It can dynamically analyze the changes in groundwater patterns.

The groundwater monitoring system relies on existing GPRS (or CDMA, 4G, NB IoT) wireless networks for construction, which has the advantages of low investment cost, fast construction speed, and no communication distance restrictions. The system supports the groundwater communication protocol of the Ministry of Water Resources and has been widely applied in national groundwater monitoring projects in various regions.

The water level monitoring instrument for dams is divided into two parts: real-time monitoring equipment for groundwater on-site and display instruments for monitoring centers.
The on-site real-time monitoring equipment for dam water level monitoring is divided into groundwater input type water level gauge or groundwater input type water level and temperature integrated measurement water level gauge.
The main function of the dam water level monitoring instrument display instrument is to display real-time measurement data of the water level gauge on site. (Display * new water level data)
The dam water level monitoring instrument WH6 has the function of real-time digital display and intelligent alarm. Intelligent alarm can be triggered when the groundwater level is too high or too low.
The dam water level monitor display instrument WH6, combined with a paperless recorder, can also automatically record and record data on water level, height, and temperature in real-time.
The wireless transmission system for dam water level monitoring can also directly display the depth of the water level measured by the input water level gauge in real-time through a mobile phone.

WH311Before and after the dam gateWater level measuring instrumentAccording to the principle of hydrostatic pressure, which is proportional to water depth, a water pressure sensitive integrated component is used to make a sensor probe for a deep well water level measuring instrument. When the sensor probe is fixed at a certain underwater measuring point, the height of the water column pressure above the measuring point plus the elevation of the point can indirectly measure the height of the water level (the distance from the water surface to the wellhead); The actual height of the liquid level in the deep well above the sensor probe is directly measured.

The engineers of Dongfang Wanhe Instrument have helped dozens of users, including Guizhou Geological Bureau, Jilin University Earth College, Xinjiang Seismological Bureau, to achieve real-time monitoring of deep well liquid level and low level pump shutdown functions. Now let's focus on analyzing the Guizhou Geological Bureau's solution for deep well liquid level display and pump shutdown:
 

 
 
 
 WH311Before and after the dam gateIntegrated monitoring solution for water level gauge, water level monitor, and liquid level temperature:
Connect the liquid level probe WH311 directlyAt the bottom of a 1000 meter deep well, it is important to protect the steel wire cable during placement (if the cable is damaged, there will be no output signal). The wiring diagram is as follows

 
 
 
 
 
 
    twoConnect the signal line of the WH311 liquid level probe to the WH6 display instrument, which will display the current real-time liquid level of the deep well in real time, and then adjust the AH AL value (AH is the high level alarm value, AL is the low level alarm value, which can be set by the user according to the on-site process requirements). We set it to 50 meters. When the actual measured liquid level value is less than 50 meters, the relay acts and the alarm is connectedSound and light alarm will be issued. Thus achieving the function of low water level alarm.It can also form a circuit with the normally closed point of the low liquid level alarm and the intermediate relay that controls the deep well pump. It can also function as a low level pump stop, protecting the deep well pump and preventing the problem of idle running and dry burning.
