deadband (extending 1.0 inc hes (25 mm) up from the
bottom of the Peak Combo Sensor).
Cabling between the proces sor board and the veloci t y
sensor may be bad.
Veloci t y parameters may require adjustment.
Possible
Solutions
Clean the sensor’s trans mit/ receive surfaces.
Verify that minimum flows are occurring outside the
sensor deadband.
