Wide Range Of Applications Stable Performance All-In-One Flew Meter
Throttle device has many advantages, but generally feel the
pressure line in the field laying workload, but also prone to
leakage, blockage and other problems. In recent years, differential
pressure transmitters have made rapid development, not only compact
size, and stable performance, easy to adjust, basically no need to
adjust the zero point in the process of use. These advantages have
contributed to the development and application of one-piece
throttle flowmeter (including orifice plate, annular orifice plate,
nozzle, etc.).
All-In-One Flew Meter Working Principle
Installed in the pipeline internal orifice or nozzle and other
throttling parts, due to the throttling parts of the aperture
smaller than the inner diameter of the pipe, when the fluid flow
through the throttling parts, the flow beam cross-section suddenly
contracted, the flow rate accelerated. The static pressure of the
fluid at the back end of the throttle is reduced, so the static
pressure difference is generated before and after the throttle,
which has a definite numerical relationship with the fluid flow
rate, in line with Q = K.√△P. The differential pressure transmitter
(or differential pressure meter) is used to measure the
differential pressure before and after the throttle to achieve the
measurement of the flow rate.
All-In-One Flew Meter Design Feature
1. The orifice plate calculation adopts international standard and
processing.
2. Standard type throttling device can be put into use without real
flow calibration.
3. One-piece orifice plate is easier to install, no need to draw
pressure pipe, can be directly connected to differential pressure
transmitter and pressure transmitter.
4. Wide range of applications, all single-phase flow can be
measured, part of the mixed-phase flow can also be applied.
5. The structure of the throttling device is easy to copy, simple,
solid, stable and reliable performance, long service life and low
price.
