VM-10AS Series

Reed Switch Type
Water Level Gauge■ Accurate measurement: Direct measurement of the water level change with the float
allows accurate measurement (±1.0cm), regardless of the measurement scope■ Simple measurement principle: The water level is converted to electronic signal by turning
ON/OFF the lead switches with magnet

This product has a number of reed switches vertically at 1cm intervals. The float with a built-in permanent
magnet moves up and down according to change in the water level, and it turns on the switch at a level inthe gauge to sense the water level.
The water level is converted to electronic signal, which is input to a water level coder installed at a facility,
allowing BCD output and recording to a SD card.
