From time to time, some users have come to ask us about the specific purpose and usage of the purge flowmeter. As the earliest manufacturer of domestic purge flowmeters, Changzhou Chengfeng Instruments hereby organizes some of the most ambiguous questions for everyone and conducts science popularization.
The purge flowmeter is different from the air blowing device. In general, the blowing device on the power plant's pulverized coal pipeline uses clean nitrogen and other inert gas to backfetch the pressure-recovery pipeline to prevent the pressure-reducing port from being blocked by the coal dust. In addition to this effect, the purge flow meter has more effects. The purge flow meter produced by our company utilizes a constant flow valve in combination with a metal tube float flow meter and a glass rotor flow meter to achieve flow measurement and ensure constant output of the flow. Can be used to measure gases, liquids. The flow meter measures the flow of the purge medium instead of purging the flow meter. For inlet and outlet pressure changes, the use of a purge flow meter ensures constant output.
Changzhou Chengfeng Purge Flowmeter is equipped with a constant flow valve with RE type with constant inlet pressure change and RA type with constant outlet pressure change. In the actual use of customers, there are several branch flows in the main pipe, if it is closed The branch pipelines will cause changes in flow due to changes in other branch pressures, such as the installation of purge flow meters, which will maintain the output flow rate. When the outlet pressure changes, it can be used together with the differential pressure transmitter to determine the liquid level and the liquid density.
Changzhou Chengfeng Purge Flowmeter has two types of single-table and panel type. The panel type is available in one-way, two-way, or multi-way, equipped with filters and pressure gauges. Material is 304 stainless steel and 316, 316L stainless steel, the connection can be customized according to customer needs.
So must the purge flow meter be used? According to customer site requirements. Accurate and stable measurement requirements, users of high liquid level requirements, it is recommended to use.
What is the role of purge flow meter? How is it purged? ? Is it necessary to use?
For the purge flowmeter, many users in the industry may only smell its name but do not know its purpose. Actually, the purge flowmeter is used as an auxiliary tool for the rotor (float) flowmeter, and the optimization aid is quite awesome.
