Level sensors for water treatment

What the sensor needs to do

Sludge, scale or biological deposits may persist at the tip after a vessel has emptied.

Installation and integration

Keep the sensing tip out of a stagnant branch that remains full after the main pipe drains. In a dirty service, plan an isolation and cleaning method. If operators need a percentage or remaining volume, keep a suitable continuous transmitter in the design.

A representative test plan

Compare clean water, the expected treated or dirty water, drained residue and any cleaning chemical. Record both the sensor indicator and the PLC state. Simulate loss of power and a disconnected signal in a controlled commissioning procedure.

A common selection mistake

Using a low-mounted wetted sensor as proof that a pump has adequate suction head. Local presence does not establish flow, pressure or the absence of cavitation.

What to include in your inquiry

• Water quality and expected deposits
• Tank or pipe drawing with mounting position
• Alarm or control action at high/low level
• Maintenance access and required documentation
