Ring Pressure Gauge

In addition to the liquid column manometer can be used as a differential manometer, in the measurement also often use ring type differential manometer to measure the pressure difference.Ring balance differential pressure gauge, also known as ring balance differential pressure gauge, can be regarded as a rotating u-tube. The rotation Angle of the differential gauge is only related to the differential pressure, not to the amount and density of the working liquid in the ring. Moreover, ambient temperature has little effect on the meter reading, and the amount of liquid in the ring does not need to be kept strictly constant. In use, this instrument can change its measuring range as needed, just by changing the weight of its heavy hammer.Through the drive mechanism, the turn of the ring to the pointer, can indicate the size of the pressure. The ring differential gauge is most suitable for measuring small differential pressure and is often used with throttling devices to measure flow. Can also be used alone to measure differential pressure, pressure.
