Maintaining the HVFlo breather valve
The ceramic depth sensor used in a MACE Doppler ultrasonic area/velocity sensor measures the hydrostatic
pressure of the stream depth. This sensor is vented to atmospheric pressure via a vent tube inside the sensor
cable. This vent passes through the HVFlo XCi specific area/velocity sensor connector and into the HVFlo
XCi enclosure. Since the HVFlo XCi has a waterproof environmental rating (IP68), the enclosure is made to
"breathe" via a hydrophobic membrane "breather valve" (made by Gore
®
).
WARNING: Although the breather valve is both hydro- and oleo-phobic, in the case
where the HVFlo XCi has been submerged, the breather valve MUST be replaced
before being re-deployed.
The following procedure should be followed i order to replace the breather valve:
1. Locate the breather valve on the inside right of the enclosure.
