3.3 INSTALLING THE TEMPERATURE SENSORS

When properly installed, the temperature sensors will only measure the inlet and outlet

temperatures of the heat exchange circuit where the energy measurement is being made. Before

you install the sensors, the entire piping system should be ushed and free of debris.

3.3.1 Direct Insertion Temperature Sensors

System-40 BTU meters congured with direct insertion temperature sensors are provided with

one sensor pre-installed in the ow sensor body. The second sensor must be installed in the

pipe opposite that of the ow sensor as shown below. The tapered sensors are provided with an

M10 threaded tting and a at sealing gasket. For standard installations, an M10 x NPT bushing

is provided for use with a customer supplied line size tee. The torque required to properly

install the temperature sensors is 4lb-ft.
