In order to meet the actual working conditions on site and customer needs, YFM-100 series Ultrasonic Heat Meters provide clamp-on type, insert type, and pipe segment type for users to choose from.
The clamp-on type is divided into: standard small S1, standard medium M1, standard large L1, high temperature small S1H, high temperature medium M1H, high temperature large L1H;
Insert type is divided into: standard insert type, water meter insert type, cement insert type, large cement insert type, super large water meter insert type;
The pipe section type is divided into: standard pipe section type (DN50mm~1000mm), m-shaped pipe section type (DN15~40), and sanitary type (DN15~100).
clamp-on type sensors
During installation, the sensor is directly tied to the outer wall of the pipe to be measured. There is no need to break the pipe or stop production. It has the characteristics of simple installation and no pressure loss.
