tank. Refer to the procedure below for the installing a plastic bung kit.
•
For Differential Pressure Prophet installations, verify if a mechanical agitation device
exists within the tank, which could damage the sensor.
•
For Ultrasonic Prophet installations, verify no obstructions exist within the tank which
could alter the ultrasonic readings.
