Recommended Installations

Gas Service

Secure the electronics above the sensor to prevent condensable
liquids from collecting in the impulse piping and the DP cell.

Liquid Service (up to 250 °F (121 °C))

Secure the electronics below the sensor to ensure that air will not be
introduced into the impulse piping or the electronics.
