GENERAL
CONSIDERATIONS
The quality and accuracy of flow, level, or pressure measurement depends
largely on the proper installation of the transmitter and its associated impulse
piping and valves. For flow measurement, proper installation of the primary
measuring element is also critical to the accuracy of the measurement.
Transmitter installation should minimize the effects of temperature gradients
and temperature fluctuations, and avoid vibration and shock during normal
operation. Take care when designing the measurement to minimize the error
caused by incorrect installation. The ambient temperature of the transmitter
environment affects the qualified life of the transmitter (see Figure 2-1).
