Program the Electronics with the application data to obtain the calculated separation distance.

Measure the circumference of the pipe and mark a position at the halfway point. (Outside Diameter of the pipe times 3.142 divided by 2). Apply grease to the second sensor and plug the blue connector into the top of the sensor. Follow (figure 13) next diagram to set up the sep distance.

Sensor stems to face each other

FLOW

Using a marker pen or a strip of ticket paper mark around the pipe from the front edge of the first sensor “A” till you reach the half way point of the pipe. From “B” measure the separation distance calculated by the electronics. Mount the second transducer as per the first with the stem facing the other transducer.

Press ENTER to view the flow. The signal strength should be greater than 50%. Should you have difficulty getting a signal remove the sensor from the Gull wing re-apply the grease and try to find a signal by moving it with your hand.

Red connector upstream

FLOW

Position the Red sensor cable upstream and the Blue cable Downstream. The Electronics will display a positive flow reading with cables in this orientation. If the unit displays a negative reading the cables have been connected into the wrong sensors.
