Install the temperature and pressure sensor in a location that will be easy to perform
periodic maintenance. Install shut-off valves upstream and downstream of the
sensors to aid installation and maintenance. Install a strainer or other ltering device
upstream of the ow and pressure sensors.
The rst length of straight of pipe connected to the ow sensor must be a
minimum of 3” long prior to a bend for the sensor to register a proper reading.
using Fluids otHEr tHan watEr; glycol, mEtHanol, EtHanol
Recommended Fluid Concentration
Heating: 0-50%
Cooling: 0-30%
Fluids other than water must factor that the Kinematic viscosity less than or
equal to 2 mm2/s (cSt). Heat measurement calculations performance will be
affected by the viscosity.
While initially lling the system take care to not produce any water hammer
at the sensor. Slowly increase initial ow and pressure to the sensor. Failure to
do so can cause the sensor to fail.
INSTALLATION
No pipe tape/dope
should be used on
threads.
Sensor can be mounted
Vetically or horizontally
within a 180 arc.
Sensor CANNOT be
mounted pointing below
this line or downwards.
