Outer tie sensor parameters

Insert the sensor parameters
Plug-in sensor is used on test pipes use special drilling tool in case of non-stop on-line punch to make direct contact with the sensor and the measured media in order to achieve an installation of flow measurement sensor which solves the outer tie When the sensor in the measurement pipe fouling thicker difficult time measuring the received signal and the signal attenuation problem, with no cut-off installation, maintenance-free, regardless of the diameter, no pressure loss characteristics.
When the pipe is made of carbon steel or stainless steel can be welded directly to install, for not directly welded pipes, such as cast iron, glass, steel, PVC, cement pipe and other manufacturers to be equipped with a dedicated pipe hoop made before installation, to prevent leakage, please when the user ordering provide accurate test tube outer diameter or circumference.

Pipe section sensor parameters
Pipe-stage sensor is flange to a measurement sensor and measured pipe directly connected to the pipeline, which solves the outer tie type sensor and plug-in sensor in the installation process for the pipe parameters due to human or inaccurate due to measurement error caused by the decline in accuracy problems, has high accuracy, good stability, maintenance-free characteristics, is the future direction of the ultrasonic flowmeter.
