variousLiquids, gases, natural gas and steamFlow measurement
orifice flow meterCauses local contraction near the throttling member and increases the flow rate, There is a static pressure difference between the upstream and downstream sides. According to the principle of flow continuity and Bernoulli's equation, the relationship between differential pressure and flow rate can be deduced and the flow rate throttling device is also called a differential pressure flow meter. It is widely used in the flow measurement of gas, steam and liquid. HaveSimple structure, easy maintenance, stable performance and reliable use and other features.
FTP-1800 series clamp-on single-hole orifice flow meter fluid must fill the pipe, and the flow is continuous. The fluid should not change phase (from liquid to gas or vice versa) near the throttling device; the fluid should be single-phase (gas or liquid) or can be regarded as single-phase [for example, there are no more than 2% (mass component) of uniformly dispersed solid particles in the gas flow, and no more than 5% (volume component) of uniformly dispersed bubbles in the liquid flow].
■ The throttling device has a simple and solid structure, stable and reliable performance, and a long service life.
■ Wide range of applications, all single-phase flows can be measured, and some mixed-phase flows can also be applied
■ The standard throttling device does not require real flow calibration and can be put into use
■ Clamp-type orifice plate can be directly connected to differential pressure transmitter and pressure transmitter
■ High measurement accuracy and wide range ratio
■ Resistant to high temperature and high pressure, suitable for various working conditions
■ It uses a wide range of media and can measure various liquids, gases and steams.
