Technical data at a glance

10.1.1

Application

• Measuring the flow rate of fluids in closed piping systems.
• Applications in measuring, control and regulation technology for monitoring
processes.
10.1.2

Function and system design

Prosonic Flow operates on the principle of transit time difference.
The measuring system consists of a transmitter and sensors.
Two versions are available:
• Version for installation in the safe zone and for explosion hazardous Zone 2
• Version for installation in explosion hazardous Zone 1 (see separate additional explo-
sion hazardous documentation)
Transmitter:
• Prosonic Flow 93
Measuring sensors:
• Prosonic Flow P (for chemical and process applications)
for nominal diameters DN 50...4000
• Prosonic Flow W Clamp On version (water/wastewater applications)
for nominal diameters DN 50...4000
• Prosonic Flow U Clamp On version (water/ultrapure water applications)
for nominal diameters DN 15...100
dedicated for plastic pipes
• Prosonic Flow W Insertion version (water/wastewater applications)
for nominal diameters DN 200...4000
• Prosonic Flow DDU 18 sound velocity measuring sensors
for nominal diameters DN 50...3000
• Prosonic Flow DDU 19 wall thickness measuring sensor
for wall thicknesses of 2...50 mm for steel pipes and
for wall thicknesses of 4...15 mm for plastic pipes (for limited service at PTFE
or PE pipes)
10.1.3

Input

Flow velocity
(transit time difference proportional to flow velocity)
Typically v = 0...15 m/s with the specified measuring accuracy for Prosonic Flow W/P
Typically v = 0...10 m/s with the specified measuring accuracy for Prosonic Flow U
Over 150 : 1
Status input (auxiliary input):
U = 3...30 V DC, R = 5 kΩ, galvanically isolated.
i
Configurable for:
totalizer reset, measured value suppression, error message reset.
