10 Technical data
10.1 Brief technical data guide
10.1.1 Application
• Measuring the flow rate of fluids in closed piping systems.
• Applications in measuring, control and regulation technology for temporary process
surveying.
10.1.2 Function and system design
Measuring principle Prosonic Flow 92 operates on the principle of transit time difference.
Measuring system The flow measuring system consists of a transmitter and sensors.
Transmitter:
• Prosonic Flow 92
Flow measuring sensors:
• Prosonic Flow W
for nominal diameters DN 50...4000
• Prosonic Flow U
for nominal diameters DN 15...100
• Prosonic Flow P
for nominal diameters DN 50...300
10.1.3 Input
Measured variable Flow velocity (transit time difference proportional to flow velocity)
Measuring range Prosonic Flow W, P, U sensors typically v = 0...7 m/s with the specified measuring accu-
racy
Operable flow range Over 70 : 1
Input signal Current input: 4...20 mA, galvanically not isolated
10.1.4 Output
Output signal Current output:
Active 4...20 mA, R
L
= 0...1 kW, galvanically isolated (from ground and analog input)
Signal on alarm Current output
→ failsafe mode selectable
Load See “Output signal”
Low flow cut-off Switch point for low flow cut-off is selectable.
Galvanic isolation All circuits for outputs and power supply are galvanically isolated from each other.
