9.3.10 Throttles
Throttles (orifices) are to be installed in all by-pass lines to ensure balanced operating conditions
for temperature control valves. Throttles must also be installed wherever it is necessary to
balance the waterflow between alternate flow paths.
9.3.11 Thermometers and pressure gauges
Local thermometers should be installed wherever there is a temperature change, i.e. before
and after heat exchangers etc.
Local pressure gauges should be installed on the suction and discharge side of each pump.
