MJ2210-12C型音速喷嘴式燃气表检验装置是实现多表位全自动检定的设备,通过光电采集实现燃气表流量值采样,因为不同厂家生产的燃气表形状不同,光点所在高度也不相同。用于同一生产厂家的燃气表进行检定非常方便,但计量检定单位需要对不同厂家的燃气表进行检定,需要调整光点采集系统的位置。该装置采用手动调节机械限位装置来实现光标位置的调整给工作带来很大的不便,因此需要改进。一、音速喷嘴式燃气表检验装置的原理和构造音速喷嘴式燃气表检验
MJ2210-12C sonic nozzle gas meter test device is to achieve multi-epitope automatic verification of equipment, through the photoelectric capture gas meter flow value sampling, because different manufacturers produce gas meter shape, the spot height is not the same. Gas meter for the same manufacturer for the test is very convenient, but the measurement verification unit need to test the gas meter from different manufacturers, you need to adjust the location of the spot acquisition system. The device uses manual adjustment of the mechanical limit device to achieve the adjustment of the cursor position to bring great inconvenience to the work and therefore needs improvement. First, the sound velocity nozzle gas meter inspection device principle and structure Sound velocity nozzle gas meter test
