(max. 30°) will help to avoid these problem areas,
but use caution. Excessive angles will cause
bearing drag at lower flow rates.
On a vertical pipe run locate the sensor where the
flow is upward. If downward flow is necessary
the system must be designed to prevent air/water
vapor pockets from developing in the pipe which
will affect the performance of the sensor.

Vertical mounting is recom-
mended to provide best
overall performance.
Special Considerations
For Hot-Tap installations allow at least 3 feet of
vertical clearance for sensor installation plus the
distance required for the isolation valve and fittings
attached to the pipe. More clearance may be
necessary to suit the drilling machine used during
sensor installation.

2.3 Sensor Wiring
Both Standard and Hot-Tap sensor
versions include 25 feet of cable. The
cable may be extended up to 200 feet
without amplification. A
