Vortex flowmeter selection recommendations
1 in general, the flange clamping type flowmeter is recommended. It is more compact than the flange connection type flow meter, and the price is lower.
2 explosion proof type flowmeter should be used in explosion hazard site. The flameproof instrument allowed for the 0 types of dangerous places, at the same time flameproof instrument is not allowed in the scene to open the shell circuit adjustment, therefore, strongly recommend that users try using this type of explosion-proof vortex flowmeter. Only in special circumstances to consider the use of explosion-proof type flow meter.
3 should be carefully selected DIN/ANSI standard flow meter. The actual diameter of the DIN/ANSI instrument is not consistent with the diameter of the GB international pipeline. When the pipeline is GB, the flow meter which is manufactured according to the DIN/ANSI standard will meet the problems of installation and use. Only the pipeline is the case of the DIN/ANSI pipeline, the flow meter of the DIN/ANSI standard is selected.
4 standard material 1Cr18Ni9Ti can be used in the vast majority of conventional media, including a number of corrosive medium and saturated steam, superheated steam. Special materials are not used in the non special high corrosion media, because the latter is expensive and the processing time is long.
5 for the total amount of measurement, especially for trade settlement, it is recommended to use the pulse signal output of the 10VME flow sensor instead of the 10VTE flow transmitter
Reason: the pulse signal output from the flow sensor is directly separated from the vortex, which has the highest cumulative accuracy. Pulse signal transmission effect is better, at the same time, the price is lower than the flow transmitter. Flow transmitter is analog signal output, full range precision, cumulative accuracy is poor, not suitable for the total amount of measurement purposes.
