Operating conditions: Environment
Ambient temperature range
Transmitter
–25 to +60 °C (–13 to +140 °F)
At ambient temperatures below –20 °C (–4 °F) the readability of the display may be impaired.
Install the transmitter at a shady location. Avoid direct sunlight, particularly in warm climatic regions.
Sensor
–20 to +80 °C (–4 to +176 °F)
Optional: 0 to +130 °C (–32 to +265 °F)
It is permitted to insulate the sensors mounted on the pipe.
Connecting cable (sensor/transmitter)
• Standard (TPE-V): –20 to +80 °C (–4 to +175 °F) (multi core)
• Standard (PVC): –20 to +70 °C (–4 to +158 °F) (single core)
• Optional (PTFE): –40 to +170 °C (–40 to +338 °F) (single core)
!
Note!
• It is permitted to insulate the sensors mounted on the pipes.
• Mount the transmitter in a shady location and avoid direct sunlight, particularly in warm climatic
regions.
Storage temperature
The storage temperature corresponds to the operating temperature range of the measuring
transmitter and the appropriate measuring sensors and the corresponding sensor cable (see above).
Degree of protection
Transmitter
IP 67 (NEMA 4X)
Sensors
IP 67 (NEMA 4X)
Optional: IP 68 (NEMA 6P)
Shock resistance
according to IEC 68-2-31
Vibration resistance
Acceleration up to 1g, 10 to 150 Hz, according to IEC 68-2-6
Electromagnetic compatibility
(EMC)
As per IEC/EN 61326 and NAMUR Recommendation NE 21.
In the frequency operating range of the sensor (1 to 3 MHz), failsafe values up to 5 V do not affect
the measured values.
9.1.9
Operating conditions: Process
Medium temperature range
Flowrate measuring sensors Prosonic Flow W (clamp-on):
–20 to +80 °C (–4 to +176 °F)
Optional: 0 to +130 °C (+32 to +266 °F)
Medium pressure range
(nominal pressure)
Perfect measurement requires that the static fluid pressure is higher than vapor pressure, to avoid
outgasing.
Pressure loss
There is no pressure loss.
