Description<\/h3>\n\n\n\n

This standpipe water level meter measures underground water level by lowering the probe through a PVC pipe or inclinometer casing in the borehole, and when the probe reaches the water, the buzzer rings and the lamp turns “on”. At this time, the operator just reads the level.<\/p>\n\n\n

Operation<\/h3>\n\n\n\n

When the water level probe reaches underwater through the PVC pipe that is installed with a water level filter, the sensor connects to the electrode, causing the buzzer to ring and the lamp to turn on. At that moment, the operator reads the tape measure connected to the probe.<\/p>\n\n\n\n
