ABB Liquid Level Relay, 0.1 to 1000kΩ Sensitivity, 1 Output - CM-ENS Series - 1SVR730850R0200 CM-ENS.21S
You won't feel drained by tank management if you use this liquid level relay from ABB. It controls and regulates liquid levels and you can use the handy device for either overfill or dry-running protection. Simply select the up or down function on the front face of its potentiometer for snappy manual setting. You can tune into its awareness, thanks to adjustable response sensitivity that ensures its accuracy is spot-on. There's little chance of this relay gathering dust, as its IP50-rated housing is protected against airborne contaminants.
