Cost-effective submersible level sensor for water level measurement in borewells up to 100m depth. 4-20mA output, 316 stainless steel construction, IP68 rating.
The LMK307 submersible level sensor is a cost-effective solution for measuring water levels in borewells with depths of up to 100 meters. This makes it suitable for a wide range of applications, including groundwater monitoring, irrigation, and water management. The sensor has a 25mm diameter and a 300mm length, making it compatible with most borewells. It is constructed from 316 stainless steel for corrosion resistance and long life in harsh environments.
The LMK307 is a hydrostatic level sensor, which means it measures the pressure of the water column above the sensor to determine the water level. The sensor has a 4-20mA output signal that is proportional to the water level. The output signal can be connected to a variety of data logging and display devices, making it easy to monitor the water level in the borewell.
The LMK307 is easy to install and use. The sensor is simply lowered into the borewell until it reaches the bottom. The sensor can be permanently installed in the borewell, or it can be used for temporary measurements.
In addition to its use in borewells, the LMK307 can also be used in other applications where water level needs to be measured, such as tanks, reservoirs, and rivers.
