I want to monitor the water level in a well or bore, the Senix Ultrasonic Level Sensor won't work... what other options do I have?
A 4-20mA, two wire loop powered pressure sensor/transducer.
A pressure sensor with 4-20mA output can be used to monitor the pressure at the bottom of your well or bore. Translating pressure to depth can provide a water level measurement.
In terms of recommended brands or models, Observant don't officially have a favoured sensor but we have in the past seen success with :
Keller - Acculevel
Dwyer - SBLT2
Seametrics - EcoPRO / PS98i
Feel free though to send through specifications for other models you're considering and we'll take a look and let you know!
