Portable Ultrasonic Flow Measuring
System
prosonic flow 92
Temporary volume flow measurement of liquids
with "Clamp On" sensors
Features and benefits
• Portable transmitter, battery operated,
for temporary measurements
• Built-in data logger with a capacity of
40000 measuring values
• Site Setup operating menus for
straightforward commissioning of up to
20 measurement sites
• "Clamp On" sensors, non-contact
measurement technique
• The sensors are affixed to the piping
from the outside
• Very wide range of nominal diameters
Sensors U DN 15...100
Sensors W DN 50...4000
• Wide temperature range of
–20...+80 °C
• Measuring transmitter in protected
handheld housing in: IP 50
• Sensors U in: IP 52
Sensors W in:
– IP 67 Sensorbody
– IP 52 BNC adapter
• Interfaces
– Data readout software for use with a
personal computer
– Current in- and outputs (4...20 mA)
Application
Ideally suited for temporary, bidirectional
measurement of pure or slightly soiled
liquids with a gas content of < 1% or a
solids content of < 5%.
• Application examples:
– Water, wastewater etc.
– Ultrapure water with low conductivity
– Process facilities
• The "Clamp On" sensors are equally
suitable for homogeneous piping as for
piping made of composite materials:
– steel, plastic, GRP and glass pipes
– Lined pipes

  • Page 2: Function And System Design

    Prosonic Flow 92 Function and system design Measuring principle Prosonic Flow operates on the principle of transit time difference. An acoustic (ultrasonic) signal is transmitted in both directions from one measuring sensor to the other. As the signal propagation velocity of the waves is less when the waves travel against the direction of flow than along the direction of flow, a transit time difference occurs.

    Prosonic Flow 92 Operating conditions Installation conditions Installation instructions Mounting location Correct measuring is possible only if the pipe is full. Avoid the following locations: • Highest point of a pipeline. Risk of air accumulating. • Directly upstream of a free pipe outlet in a vertical pipe.
  • Page 11 Prosonic Flow 92 Orientation Vertical Recommended orientation with upward direction of flow (View A). Entrained solids sink down. Gases rise away from the flow measuring sensor when liquid is not flowing. The piping can be completely drained and protected against solids build-up.
