The Mechanism of Non-Contact High Pressure Water Injection Flow Meter for Plunger Pump

As an important method to relieve the coal-rock dynamic disaster, the water injection technology has drawn increasing attention in recent years. It is important to monitor the water injection condition with a stable method. What can measure the injected water is the non-contact high pressure water injection flow meter using the magnetic technology. The data can reflect the movement of the coalbed and effect of the risk relieving work. With the use of the non-contact magnetic measurement technology, this system has very good anti-jamming and environmental capability. It also implements the remote monitoring with the date transfer system. This new design can not only solve the digital monitoring water injection, but also improve the safety condition of mining.
