FB-3500 Bi-Directional Insertion Electromagnetic Flow Meter Manual 05/14 - 0718-3 Page 18

WARNING

SYSTEM MAY BE UNDER HIGH PRESSURE. When removing the ow meter, be sure to hold

the electronics enclosure rmly by hand before slowly loosening the positioning clamping

nut. Failure to do this will allow the pressure in the pipe to suddenly and rapidly force the

meter from the pipe causing serious injury. The meter could also be damaged or break apart

causing a break in the water seal with the resultant loss of large amounts of water. The hand

effort required to hold the meter will be 0.11 times the pipe pressure.

Step 1:

Slowly loosen the position

clamping nut while

maintaining a rm grip on the

enclosure to counteract the

effect of pressure in the pipe.

Step 2:

Carefully withdraw the

ow meter stem from

the pipe until the sensor

head is fully inside the

hot tap adapter.
