Flow and temperature in one body
Cooling circuits usually need both readings — flow to confirm the pump is delivering, temperature to confirm the heat is being carried away. Fitting two instruments means two tappings, two cable runs and two inputs. This unit measures both at one point, which also means the two readings refer to the same place in the line rather than to points metres apart.
The three-colour display
The display changes colour with the output state, so an operator walking past sees whether the circuit is inside its window without reading the number. On a machine with several cooling
