Product Description

The IWSL potable water submersible pressure sensor can be used in many applications throughout the freshwater supply system such as monitoring river levels, surface and underground reservoir depth, water tower height, groundwater borehole depth and aquifer water levels.

The IWSL provides an analogue signal which is proportional to the hydrostatic pressure of the water column above the submerged sensor. To accommodate the standardised signal used in a particular water region there is a choice of outputs from low power consumption millivolt or voltage output for remote isolated installations and OEM product integration to 4-20mA current loop for water process and distribution control systems.

Product Help

Long cable length

We require 100 metres of cable, but only 10 metres of the cable will be submerged in fresh (potable) water tanks, so can the IWSL be supplied with that length of cable?

The submersible cable fitted to the IWSL includes air breather tube for provide an atmospheric pressure reference for automatically correcting the water pressure reading. This cable is quite expensive for running along the ground, so you may want to consider using a vented junction box where the cable exits the tank, and run a cheaper sensor cable without a breather tube along the ground.

Sailboat water tank level with Arduino

I would like to measure water level in a water tank on a sailboat using an Arduino board. The water level is approx 0-0.6m

We would suggest the 5 volt input, 0.5 to 4.5 volt output option for compatibility with the available sensor power supply and analog inputs of the Arduino electronics.
