Q:Why is in the gas flowmeter type to a security gate

But simple components do not need to be certified, such as thermocouples, thermal resistors, switches, etc., even if no authentication is available, they can also be directly added to the safety barrier.

Q:What is mass flow meter?

Based on the Coriolis mass flowmeter, T type vibration sensor in two parallel tubes, central driving coil is arranged at both ends with pick-up coil, mass flowmeter, direct measurement of mass flow rate through the flow of medium, but also can measure the density of the medium and the indirect measurement of the medium temperature. Mass flowmeter is an important flow measuring instrument. Mass flow meters are measured by sensible heat.

Q:What are the technical parameters required to select the electromagnetic flowmeter?

Flow, caliber, measured medium, temperature, output mode.

Q:How do you measure a flow meter? What methods do you usually use?

The online test requirement of the flowmeter work in the practical working conditions, by using the standard device will have been authorized by the state, has determined the standard flowmeter colonel. The level of accuracy (or flow standard device) on circuit connected to the meter, with the method for the calibration of flowmeter tested medium so this method to reliably determine the working performance of the flowmeter, can obtain higher accuracy. Due to the standard flow meter (flow standard device) affect the transport and installation difficulties, not only the high cost of online approval approved, and sometimes simply can not be achieved, so the use of online verification method in China's natural gas measurement in a few occasions.

Q:What is the working principle of the V cone flowmeter?

According to this principle, the flow meters include orifice plate flowmeter, nozzle flow meter, 1/4 round nozzle flowmeter, venturi tube flowmeter, V plug pipe flowmeter.

Q:What is the difference between electromagnetic flowmeter, flow transmitter and flow sensor?.

Electromagnetic flowmeter is a general term, it usually has two types of integral and split type. Integrated flow sensors and flow transmitters are all integrated into the flowmeter body, which is the most common.

Q:What is the K-factor (K value) in the flowmeter? How do I calculate it?

K new =K original (1+- error) K was originally factory calibration, if the super poor, only the K coefficient

Q:What are the characteristics of the LC gear flowmeter?

The LC series elliptical gear flowmeter is a direct reading accumulation meter which is a volumetric flowmeter measuring the sum of liquid flow through the pipeline. The utility model can be widely used for flow measurement in petroleum, chemical, medicine and health departments.

Q:Are ultrasonic level meters the same as ultrasonic flowmeters?

The same basic principle, level meter need a probe flowmeter needs only 2, but due to the direct contact to the measured liquid, to probe the package also has certain requirements, liquid level gauge due to non-contact measurement, so the requirement is not so strict, in general, are based on the principle of ultrasonic ranging. Do you want to use to measure the difference between transmitting and receiving acoustic time data, in addition, the medium level meter is generally the air, and the flow is more complex, can be liquid, gas can also be

Q:Who can tell me what flow control is used (model)?

You can use flow meters to measure the flow rate to control the related quality, because the medium is uniform and the volume of the flow is quite in line with the corresponding mass. The electromagnetic flowmeter can be used. It is recommended that the electromagnetic flowmeter of Shanghai Kent be cost-effective
