Analog Water Level Meter measures water level and water temperature at a same time by one (1) probe. The probe is slim size with 18 mm in diameter only. User can use this for small size of monitoring well/hole.
Monitoring data is read out by electric current with 4 – 20 mA, then this instrument can be connected to a data logger marketed*. To get more reliable data, user can connect this to GSM i-SENSOR Analog 4.1ch of a remote monitoring system.
* No warranty is given as to the availability to connect the instrument to all data logger.
■ Minimum 20 mm in diameter PVC pipe can be used as a monitoring well.
■ It is not required correction of atmospheric pressure because of the cable with a built-in bent tube.
■ Stainless (SUS316) is used for the sensor parts and housing, then this instrument is resistant to corrosion.
■ There is high versatility for water level monitoring.
