TF1100-DI Dual-channel Insertion Transit Time Ultrasonic Flowmeter works on the transit-time method. It is ok to measure all kinds of liquids in fully filled pipe.The Insertion ultrasonic transducers (sensors) is hot-tapped mounting, there is no ultrasonic compound and coupling problem; Even though the transducers are inserted into pipe wall, they do not intrude into the flow, thus, do not generate disturbance or pressure drop to the flow. The insertion (wetted) type has the advantage of long-term stability and better accuracy. 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
Hot-tapped installation,no pipe line flow interrupted.
No moving parts,no pressure drop,no maintenance.
Spool-piece transducer for best accuracy and better long-term stability.
Insertion dual-channel flow transducers are suitable for high temperature of -35℃~200℃.
Wide bi-directional Flow range of 0.01 to 15m/s, and wide range of pipe sizes from DN65 to DN5000.
Thermal energy measurement capability can be optional.
Data logger function.
The heat measurement function by configuring with paired temperature sensors.
