On-site analysis of application of coke oven gas cooling flowmeter

Coke oven gas has high temperature and high humidity when it leaves the factory, so we have moisture management in the process of gas transportation.

 

Electromagnetic flow meter is an inductive instrument manufactured according to Faraday's law of electromagnetic induction to measure the volume flow of conductive medium in a pipe.

 

Vortex flow meter is a volume flowmeter that measures the volume flow of gas, steam or liquid, the volume flow of standard conditions or the mass flow. Mainly used for flow measurement of industrial pipeline medium fluid, such as gas, liquid, steam and other media.

 

Magnetic flap liquid level gauge + analog liquid level transmitter, consists of two parts: liquid level sensor and signal converter. The liquid level sensor is composed of several reed switches and several resistors installed in a φ20 stainless steel protective tube. The protective tube is fastened to the outside of the measuring tube (main tube); the signal converter is composed of electronic modules, which are placed on the explosion-proof wiring at the top or bottom of the sensor. Three, the main technical parameters

Precautions for use on site

 

1) It is well known to the users that the electromagnetic flowmeter is not suitable to be installed in the occasion of strong vibration, but in the occasion of frequent change of the magnetic field, the vortex flow sensor will measure the signal output higher than the normal value.

 

3) Since the impurities in the coke oven gas are easier to crystallize, the impurities condense on the sensor head, resulting in inaccurate measurement. At elevated temperatures, volatile impurities, increase sensitivity, signal enhancement; contrast decreases. cause data instability.

 

Practical research has proved that in the field without gas flow, when the vortex flow sensor technology is in the developing and changing magnetic field, at the moment of the magnetic field change, the vortex flow sensor will sense an error signal and output, when the change process is over, the instrument is in In such a stable magnetic field, the instrument will output as a normal working signal.
