Intended Use
SensoGate® WA 131 H
CAUTION!
Observe the general requirements of protection devices to prevent pollution of potable water
(EN 1717) when drawing water from drinking water pipes.
We recommend installing a check valve on the water supply to protect the drinking water from
pollution.
We recommend installing a check valve on the water inlet e.g. on the water valve provided by
the customer or on the rinse connection of the sensor lock-gate (inlet to calibration chamber) to
pre-vent backflow of rinse or process medium or compressed air into the water pipe.
Suitable check valves made from different materials are available from Knick.
