EVA mat is a kind of foam mat for EVA sport mat, EVA Exercise Mat, and EVA training mat, made from Eco-friendly, high density, closed cell,
non-smell and non-toxic EVA foam material.
The EVA mat is offered in either 60cm x
60cm size or 100cm x 100cm size. 60cm x 60cm size. With interlocking edges, the
mats can be easy to connect together without any loose.
60cm x 60cm EVA mat is normally applied in
room, or gym. It is easy to store, more popular for the personal exercise
lovers to use at home. Also it can be a good protection for home flooring if
you are intended to set up a heavy training equipment in your house.
100cm x 100cm EVA mat is also called Martial Arts Mat,
Taekwondo mat, Karate mat, Judo mat, Jiu Jitsu mat and Aikido mat, cause it is
normally applied in dojo for Taekwondo, Karate, Judo, Jiu Jitsu and Aikido training.
Also the mat is reversible with double colors, which forms a standard size
flooring for training.

1) Turbine flowmeters are not well-suited for applications where strong vibrations are not suitable, but where the magnetic field changes frequently, vortex flow sensors will detect signal outputs that are higher than normal. Practice has proved that in the field without gas flow, when the vortex flow sensor is in the changing magnetic field, the turbine flowmeter sensor will induce an error signal to output when the magnetic field changes, and when the change is over, the instrument is in a stable magnetic field. The meter will output a normal signal.
2) Due to the high temperature and high humidity of the coke oven gas, there will be moisture in the gas transmission process. The flow of gas drives the water to reciprocate and fluctuate, creating a pulsating flow. When the vortex flow sensor is in this fluid state, the output data suddenly changes, and it cannot reflect the production status at all.
3) Because the coke oven gas has many impurities, it is easy to crystallize, and the impurities condense on the sensor head, thus causing measurement inaccuracy. When the temperature rises, the impurities volatilize, the sensitivity increases, and the signal increases; on the contrary, it decreases. As a result, data is unstable.
4) In the process of instrument wiring, the pressure lines are not true, which results in intermittent signals during transmission.
5) The instrument grounding wire does not meet the specification requirements, so that the 50Hz interference in the strong electricity will enter. When the normal signal is higher than 50Hz, it will output the normal signal, otherwise it will output the wrong signal.
Solution:
1) During the installation and connection of the instrument, ensure that every link is accurate, including the inspection of the site before installation, the wiring of the instrument during the installation, and the grounding line of the system. Data can be output accurately.
2) For the measurement system in operation, the method of "Double Track Metrology Control Engineering Network Copyright, Comparison and Confirmation" and the "Alternative Law" can be used to confirm and eliminate the malfunction of the measuring instrument in operation.
3) Periodically clean the instrument as a whole. If necessary, the sensor head of the instrument can be purged to prevent condensation of impurities at the sensor head. In the cold season, the addition of heat tracing devices in the straight section of the metering section and the meter section also helps to reduce the condensation of impurities at the meter.
4) Regularly drain the pipeline, especially the water in front of the straight pipeline, and set up regular discharges according to specific conditions to reduce the water content in the pipe section as much as possible to eliminate the pulsation in the fluid.
5) Strengthen the management of turbine flow metering system data, set up a regular print function, and analyze the operation of the instrument based on print data and production conditions.
