Measuring - Endress+Hauser Proline Prosonic Flow 91W Technical Information

Measuring

4
The measuring system consists of one transmitter and two sensors. Different versions are available depending
on the specific requirements.
The transmitter is used both to control the sensors and to prepare, process and evaluate the measuring signals,
and to convert the signals to a desired output variable.
The sensors work as sound transmitters and sound receivers. Depending on the application and version, the
sensors can be arranged for measurement via one or two traverses  ä 5.

Mounting accessories
The requisite mounting distances must be determined for the sensors. Information on the fluid, the pipe
material used and the exact pipe dimensions is needed to determine these values. The values for the sound
velocity of the following fluids, pipe materials and lining materials are stored in the transmitter:
Fluid
• Water • Glycol
• Sea water • Kerosene
• Distilled water • Milk
• Ammonia • Methanol
• Alcohol • Toluene
• Benzene • Lube oil
• Bromide • Fuel Oil
• Ethanol • Petrol
