Ultrasonic Flowmeters - Portable device (in carrying case)

Efficient flowmetering and volume counting of clean, homogeneous liquids with low gas and solids contents with single-beam measurement.

Applications 
Demineralized water for cooling purposes  
Boiler feedwater in power stations  
Pretreated wastewater in sewage plants  
Checking other flowmeters  
Oil  
Acids  
Alkaline solutions

Advantages of measuring from the outside 
Non-contact measurement  
No construction of the pipe cross-section  
No additional pressure drop  
No interruption of the process  
Electrical conductivity, pressure, density, etc. have no effect on measurements  
Easy to install  
No maintenance requirement  
Low power consumption  
Low operating costs

Configuration and function 
At the measuring point 2 ultrasonic sensors are attached to the outside wall with the aid of a mounting device.  
Each sensor emits and receives sonic pulses that are digitally converted in the signal converter.  
Data output in metric or US units via display, current, frequency and status outputs, UFM 610 P also via RS 232 interface and PC.

Reflex system: Two ultrasonic transducers (sensors) are mounted on the same side of the pipe at an angle to the pipe axis.
