Throttle device is the most historic and most extensively used flow measurement instrument. It features itself simple structure, easy installation, stable performance and high accuracy, etc merits. It can be used for flow measurement for liquid, steam and gas in modern industries. There are many kinds of throttling devices with a whole variety (being conformability with Standard GB/T2624, Standard ISQ5167-1-1991, Standard BS1042-1989 and Standard ASME) that are manufactured with advanced calculation methods and precise manufacturing means. They are applied extensively in petroleum industry, chemical industry, electrical power industry, light industry, water supply field, gas transmission field etc.

Venturi tube is high accuracy, performance stable, low pressure lost (normally is 5% ~ 20% of differential pressure) and easy to maintain. Especially in current energy saving condition, it is measurement accuracy and energy decreasing, etc, so has widely use in application.
