Portable water level and temperature measuring instrument WH311

Groundwater Monitoring Information SystemThe engineers of Dongfang Wanhe Instrument have helped dozens of users, including Guizhou Geological Bureau, Jilin University Earth School, Xinjiang Seismological Bureau, to achieve deep wellsgroundwaterReal time liquid level monitoring and low level pump stop function.

Connect the liquid level probe WH311 directly to the bottom of a deep well within 1000 meters. During the placement process, it can be lowered together with the deep well pump. During the placement process, the steel wire cable should be protected (if the cable is damaged, there will be no output signal). Connect the signal wire of the WH311 deep well liquid level probe to the WH6 display instrument, and the display instrument will display the real-time liquid level of the current deep well in real time, 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, the alarm is connected, and an audible and visual alarm is given. 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.

Many geothermal hot spring wells require real-time monitoring of liquid level and temperature changes,WH311-DZ temperature liquidIntegrated measuring instrumentSpecially designed based on the characteristics of geothermal hot spring wells, the temperature and liquid level integrated probe directly transmits dual signals of temperature and liquid level, and the dual 4-20mA transmission can also output RS485 communication protocol. Equipped with a WH6 dual channel display, the water level is displayed in real-time on the top and the temperature is displayed in real-time on the bottom.

Some on-site requirements not only require real-time display, but also include data recording function. The WH311 deep well groundwater level automatic monitoring has built-in storage and recording functions while displaying in real-time, and data can be exported using a USB flash drive. Equipped with a WH6 paperless recorder, data can be recorded once a minute for a year, and requires a USB dump interface. Data can be copied directly from a USB flash drive, and table files can be produced through the accompanying upper computer software.

Engineers from Dongfang Wanhe Instrument helped China Railway Fourth Engineering Group, China Construction Second Engineering Bureau, Gezhouba Nanjing Underground Space, etcDozens of users have implemented real-time water level monitoring with recording function, and data can be directly exported using a USB flash drive.
