TF1100-DC Dual-channel Wall-mounted Transit Time Ultrasonic Flowmeter 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. Two pairs of transducers are sufficient to cover the most common pipe diameter ranges. In addition, its optional thermal energy measurement capability makes it possible to carry out a complete analysis of thermal energy usage in any facility.

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.

Features

Data logger function.

Aluminum or Stainless steel SUS304 sensors for your optional.

Thermal energy measurement capability can be optional.

For commonly used pipe materials and diameters from 20mm to 6.0m.

Wide bi-directional flow range of 0.01 m/s to 15 m/s.

Principle of measurement

The TF1100 ultrasonic flow meter is designed to measure the fluid velocity of liquid within a closed pipe. The transducers are a non-invasive, clamp-on type, which will provide benefits of non-fouling operation and easy installation.

The TF1100 transit time flow meter utilizes two transducers that function as both ultrasonic transmitters and receivers. The transducers are clamped on the outside of a closed pipe at a specific distance from each other.  The transducers can be mounted in V-method where the sound transverses the pipe twice, or W-method where the sound transverses the pipe four times, or in Z-method where the transducers are mounted on opposite sides of the pipe and the sound crosses the pipe once.  This selection of the mounting method depends on pipe and liquid characteristics.  The flow meter operates by alternately transmitting and receiving a frequency modulated burst of sound energy between the two transducers and measuring the transit time that it takes for sound to travel between the two transducers. The difference between the transit-time is directly and exactly related to the velocity of the liquid in the pipe, as shown in below Figure.
