battery operated handheld aluminum water ultasonic flow meter with rs232 outputs

Short Description:

TF1100-CH Handheld Ultrasonic Flow Meter works on the transit-time method. The clamp-on ultrasonic transducers (sensors) are mounted on the external surface of the pipe for non-invasive and non-intrusive flow measurement of liquid and liquefied gasses in fully filled pipe. Three pairs of transducers are sufficient to cover the most common pipe diameter ranges.

User can use hand to hold as well as to operate the flow meter main unit. This flexible and easy to use flow meter is the ideal tool for the support of service and maintenance activities. It can also be used for the control or even for the temporary replacement of permanently installed meters.
