10.Connect the transducer cable, ensuring that you have observed the Upstream/Downstream orien- tation in respect to the cable and the input jack on the flow computer. If this is a dual-channel unit, make sure you are connecting the cables to the correct channel input jacks.

3.2MOUNTING TEMPERATURE SENSORS

In order to accurately measure temperature differential in energy flow loops, Siemens Energy Flowme- ters are designed to work with a pair of matched temperature sensors. These are available in clamp- on style 991T, or in insert (thermowell) style 991TW. Both styles incorporate 1000 ohm platinum RTD’s for high precision.

Clamp-on style sensors are mounted on the surface of the monitored pipe using 992EMT series mount- ing assemblies. Apply a generous quantity of the thermal couplant provided to the tip of the sensor and attach it securely to the cleaned pipe surface with the propermounting assembly. Temperature mea- surement anomalies resulting from variations in the ambient conditions can be minimized by insulating the pipe and sensor after installation.
