Product Details

Low cost insertion type Transit-time Ultrasonic Flow meter 4~20mA Modbus RS485

Low cost insertion type Transit-time Ultrasonic Flow meter 4~20mA Modbus RS485 is a transit-time ultrasonic flowmeter, it has both a transmitter and a transducer. The meter then measures the “transit time” of each signal. When the ultrasonic signal travels with the flow, it travels faster than when it travels against the flow. The difference between the two transit times is proportional to flowrate.

Insertion flow meters liquid measurement TF1100-EI provides abundant capabilities for accurate liquid flow measurement from outside of a pipe. It utilizes state-of-the-art technologies on ultrasonic transmission /receiving, digital signal processing and transit-time measurement. The proprietary signal quality tracking and self-adapting technologies allow system to optimally adapt to different pipe materials automatically. Due to hot-tapped mounting of insertion transducers, 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.

Low cost insertion type Transit-time Ultrasonic Flow meter 4~20mA Modbus Features:

1. Hot-tapped installation, no pipe line flow interrupted

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

3. Wide bi-directional flow range of 0.01 m/s to 12 m/s..

4. Wide liquid temperature range: -35℃~200℃.
5. Data logger function for insertion ultrasonic flow meter
6. Thermal energy measurement capability can be optional.
