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).
