Insertion Ultrasonic Flowmeter GPRS Solar Power Supply Digital flow meter
The Insertion Ultrasonic Flow Meter 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.
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.
High temp. Insertion transducers are suitable for high temperature of -35℃~150℃.
Wide bi-directional Flow range of 0.03 to 36 m/s, and wide range of pipe sizes from DN65 to DN6000.
Data logger function.
The heat measurement function by configuring with paired temperature sensors
