With the development of technology, there are more and more instruments for external measurement. And there are many kinds of instruments for pressure testing, and the instruments used for different methods of pressure testing are different, and the instrument for pressure testing between two points is the differential pressure gauge. The differential pressure meter is now the most widely used instrument to measure the pressure of two points. And for the differential pressure gauge there are many or more familiar, but most people look at the differential pressure gauge or installed differential pressure gauge, but also as for the differential pressure gauge how to install, I think many friends are not aware of, the following I will share in detail about the installation of the differential pressure gauge.
Differential pressure meter installation method
The first step to fix the differential pressure gauge: we can find two mounting holes in the differential pressure gauge, we need to use dowels to install it on the wall, but also can be installed on the vertical plane.
The second step is to adjust the horizontal position so that the water bubble inside the horizontal column is located in the middle.
The third step loosens the top zeroing knob by 3~4 turns, here you can mark the reading circle.
The fourth step to inject red oil into the differential pressure gauge: we need to remove the plug of the injection hole, and then fill the red oil from the injection hole, until the liquid reaches 0 scale stop, and tighten the plug.
The fifth step micro-adjustment of the red oil differential pressure gauge for zero processing. When the red oil is stabilized, we can adjust the zero knob by screwing it under normal pressure, so that the above zero point is level with the red oil level.
Differential pressure gauge features
All aluminum casting
The magnetic spiral vortex mechanism eliminates the friction caused by the gear transmission. (National practical patent product).
No need to fill the meter with liquid.
Inertia-free, drift-free pointer movement.
Essentially no hysteresis.
Excellent anti-vibration and anti-jitter performance.
Can measure positive, negative or differential pressure.
81 ranges, min -15PA-15PA.0-30PA[2],0-60Pa, max 0-210KPa.
2 sets of pressure connections (side and back) + 3 types of installation = free and flexible application.
Good accuracy, reasonable price.
Differential pressure meter installation applications
Widely used to measure fan and blower pressure, filter resistance, wind speed, furnace pressure, orifice plate differential pressure, bubble water level and liquid amplifier or hydraulic system pressure, etc. Also used for air to gas ratio control and automatic valve control in combustion process, as well as blood pressure and respiratory pressure monitoring in healthcare equipment.
The above is to share with you about the installation method of differential pressure gauge, I hope it will be helpful to you, and I hope our sharing can help you more comprehensively to know the differential pressure gauge. In addition, we must know the use of differential pressure gauge and installation methods, especially in the pressure test and instrument installation of friends should know the use and installation of differential pressure gauge. And the use of differential pressure gauge turns out to be very clever. And now the differential pressure gauge has been widely used in the filter resistance, furnace pressure, etc.. Even in medical equipment is also useful.
