Abstract
The utility model provides a counting indicating meter, a first fixed body and a second fixed body, wherein the first fixed body and the second fixed body are disposed on the rear end of the counting indicating meter and are connected with each other. By the action of mutual push between high-pressure gas or liquid entering from one end and low-pressure gas and liquid, the high-pressure gas or liquid moves gradually towards the low-pressure gas and liquid and thus a low pressure drive group disposed on the first fixed body is driven to move backward; during the moving, a magnet sleeved in a high pressure drive group in the second fixed block interacts with a magnet sleeved on the counting indicating meter, and thus a pointer on the counting indicating meter moves to an alarm threshold, a sensor above the high pressure drive group is notified immediately, and a warning lamp gives an alarm or a switch is turned off for preventing danger; and, when the pointer is out of alignment, an adjusting member can be extended into the pressure meter directly from the outside of the low pressure drive group through a tool and can be rotated for tuning the scale point positions of the pointer, without detaching of any part of the pressure meter.
