TH

Flow Measurement

Thermal Flowmeters

TH is a series of Gas flowmeter based on thermal transfer theory originally developed by Tokyo Keiso. Various types of gases are measured with high accuracy. TH consists of ;
Detector which is installed on process piping and Convertor which is connected to detector for signal processing
Various types are available to meet the requirements.
