QUAD-80 MAINTENANCE GUIDE

Checking or replacing the Quad-80 sensor is accomplished by the following steps:

Removing Quad-80 sensor:

Loosen the 3 hex bolts (2) using a 9/64” hex key.

Carefully lift the sensor housing (1) to expose the two

pairs of embedded sensors (3). If the ground wire (5) is

attached to the housing, loosen the screw (6) using a

3/32” hex key and remove ground wire from under the

screw. To remove embedded sensor elements,

remove the screws (4) holding them in place using a

3/32” hex key. The sensors and ground wire may now

be carefully removed from the meter body.

Testing Quad-80 sensor:

With embedded sensor elements (3) out of flowmeter

housing, connect cable to sensor connector (8). Set

jumper J4 on circuit board to A position for 4x output

setting. Apply 12-27 vdc power to sensor and while

looking at signal 1 output note that output changes

while a screw driver or other ferrous object is passed in

front of each of the 4 sensor elements, one at a time. If

the output does not change when screw driver is

passed in front of a sensor element, that particular

element is bad and the sensor needs to be replaced.

Installing Quad-80 sensor:

Place O-ring (7) in the O-ring groove. Insert embedded

sensor elements (3) into the sensor holes. Replace

fastening screws (4) and tighten securely. Fasten

ground wire (5) under screw (6) and tighten securely.

NOTE: If the ground wire is not going to be used,

make sure to tape the spade connector so it will not

short against circuit board and also make sure to

securely fasten the screw (6) so it will not come loose.

Finally, with ground wire and embedded sensor

elements fastened, double check that O-ring is

completely in O-ring groove and fasten the 3 socket

cap screws (2) to secure sensor housing cover (1) onto

flowmeter.
