General

GLZ Series High Pressure Flow Controller is an integral mechanical and electrical high-tech product. It assembles the high pressure flow meter, high pressure flow control valve and flow controller. The controller has a compact structure, a visual display, a high control precision, rot/corrosion proof, fouling prevention, alternating current and direct current dual-purpose, flow manual control or automatic flow control and other merits. It has been widely used for ration flow control and the projects of high pressure water/polymer injection, especially for waterflooding.

GLZ Series high Pressure Flow Auto Controller constitutes of impeller, axle and axle bearing that have been treated specifically. The meter functions well in preventing fouling of the sewage on spot and the impeller timbering assembly is easily taken out of the meter cover which are very convenient for the periodic verification of the flow meter. The executive control mechanism of the flow control valve is the alternating current electrical machine with the reduction gear. It has manual device. When the alternating current interrupts, the flow meter can work normally because of the internal power source. At this moment the valve can be controlled manually. The hand wheel is very light for the reduction gear, so the resolution ratio of regulating is relatively high. The application of the advanced electronic technology makes the complete controller have a fairly high stability and anti-jamming ability.
