Table 2: Minimum ID of pipe or connection for calibrations to be valid.
Note
The flow response of 800 Series sensors and thus their calibration may be dependent on the form of the
device attached to the inlet connection and other closely located up-stream devices.
Elbows, T-pieces, valves and filters located immediately up-stream from the flow sensor can introduce
swirling motion to the liquid flow. The swirling motion reduces the linear velocity of the flow stream.
We recommend that a straight run of pipe of more than 10 x pipe ID be used between the flow sensor and
any up-stream devices to minimize these effects.
Appropriate calibration procedures must be used to provide an accurate flow measurement with elbows
or T-pieces that must be attached directly to the inlet connection.
The 800 Series sensor is typically unaffected by the form or proximity of devices on its downstream side.
Sensor Orientation
For the best results, 800 Series sensors should be mounted with the faceplate in the vertical plane.
Mounting the device with the flow connections uppermost can help eliminate entrained air from your
system.
Flow Direction
The 800 Series Metering Flow Switch is not sensitive to flow direction. Flow can be introduced to the
sensor from either side.
NPT pipe thread connections
Pipe threads seal by making metal-to-metal contact between male and female components.
Consequently, they are particularly prone to the damaging effects of galling, which occurs when two
surfaces move against each other under pressure. When installing pipe threads it is essential to use a
high quality lubricating and sealing material.
