SIGMA ST Series Compact Ultrasonic Clamp on type flow meter without contact with the liquids.

Description
Sigma ST is very unique in its structural design. It uses a circular magnetic steel to achieve automatic connection during installation. It takes only 2-3 minutes to complete the whole process from installation to measurement. It also adopts the current popular OLED display, which makes it easy to read in low light conditions.

Sigma ST series flow meters offer users easy installation, no process downtime, no pressure loss or leak and no contamination of the medium to be measured.

Features
● With the world's most advanced time measurement chip (time resolution of SOps), a new
generation of stable flow meters has been developed
● The flow meter is fitted on the outside of the tube without additional pipe interventions required
● No expertise required, installation and measurement can be done according to the operating instructions
● No moving parts, no pressure loss. The flow meter can be installed without stopping production
