Plug in Verabar Flow Meter for Gas Measurement (A+E 87F)
The Verabar Flow Meter is a kind of differential pressure flow metering technology which is based on the operating principles of dynamic pressure changing into static pressure. The Verabar Flow Meter adopts the engineering structural design that completely accords with aerodynamics principles.
It is a kind of unparalleled sensing element with superb accuracy, functions and reliabilities. The following are typically applicable media: gas, liquid, steam, natural gas, cooling water, saturated vapor, compressed air, boiler water, superheated vapor, gas, demineralized water, gaseous hydrocarbon, liquid hydrocarbon, hot air, cryogenic liquid, producer gas, thermally conductive liquids.
The probe with a bullet-shaped section can generate precisely distributed pressure and fixed fluid separation point; the low pressure port behind the both sides of the probe and before the fluid separation point can generate stable differential pressure signal, which is anti-blocking.Internal integrated structure can prevent signal leakage, intensify the structural strength of the probe, and maintain high accuracy for a long period.
The Verabar flow meter that does continuous operation fundamentally eradicates the possibility of blocking. But the Verabav flow meter still needs anti-blocking precautions under the following conditions:
a) When the pressure pipe leaks, the high-pressure equilibrium of probe will be destroyed, and the impurities with small diameter will possibly enter the pressure port.
b) When the pipeline is shut down, the impurities with small particle may enter the pressure port due to Brownian movement of the molecular.
c) By frequently closing and opening of the system, the impurities of little particles will possibly enter the pressure port at the instant when the high-pressure area is generated, and with the time passing, the probe may be blocked.
d) The probe will possibly be blocked when there is a large quantity of tar, algae or fibrous material.
How to Select
When you are not very clear about how to select a verable flow meter model, please kindly tell us as much about the project so that we could recommend you an appropriate one, such as:
1) Where will be the meter used?
2) What's the measuring media?
3) How is the flow rate?
4) What's the pipe size?
5) How is the working condition, temperature & pressure?
6) How about the process connection and installation?
7) Other specific requirements.
