B. Installation
CAUTION: Do not exceed the pressure, temperature or power
operating ranges detailed in the Specifications section of this
manual. Dwyer Instruments shall not be liable for any damage or
injury caused by incorrect operation of their products.
1. General Considerations
It is recommended that a safety shut-off valve be installed upstream of
(before) the sensor.
All wetted parts should be checked for compatibility with the gas to be used.
If there are any incompatibilities e.g. highly corrosive gas, then the unit may
be damaged or fail prematurely. Such damage will not be repaired under
warranty.
Units should be installed in a clean, dry environment with an ambient
temperature that is as stable as possible. Avoid areas with strong magnetic
fields, strong air flows or excessive vibration.
If the gas to be used may contain particles larger than 25 microns then a
filter (25 microns or less) should be installed upstream of (before) the unit.
2. Mounting The Flow Sensor Or Flow Meter.
CAUTION: On high flow units (2.0-10.0 L/min and above) DO
NOT disassemble the shunt / mounting plate assembly or the unit
will not operate correctly and the warranty will be void.
The TFP Series of Flow Sensors and Flow Meters have no particular
installation requirements so may be mounted in any convenient position. For
optimum results the unit should be mounted with the mounting feet horizontal
on top of a flat horizontal surface. This is the same position that the unit is
calibrated in at the factory. Please contact Dwyer Customer Service if
calibration for mounting in another orientation is desired.
It is recommended that units be fixed to a suitable substrate with #4 screws
using the two mounting holes provided.
