4.5 Installing Proper Pipe Supports
To ensure accurate metering, provision of proper pipe supports is essential. This is particularly important
in applications where the pipeline is subjected to considerable vibration or where the meter measures
small quantities of process flow.
CAUTION: Support the pipeline with hold-down clamps; Never hold down the sensor body.

4.6 Heat Instulation Work
In applications where the process fluid is of low or high temperature, only the sensor body should be
heat insulated. Exclude the electronics. We recommend simple sensor lagging to facilitate inspection and
maintenance.
(1) Careful attention should be paid to the maximum permissible temperature when steam trace is applied
(see General Specifications on page 9).
(2) If steam, warm water or oil is used, secure, by metal bonding, the copper tubing, which is spirally
wound around the sensor, to the sensor body (Fig. 4.9).
NOTE: To minimize transmission of oscillation to the sensor, the spiral copper tubing should start and
end at the manifold of flanged sensor body (see Fig. 4.9).
CAUTION: 1. Do not use electric heaters which could be a source of noises.
2. Use separately-mounted type if transmitter's ambient temperature may
exceed 50°C.
