Scientific devices offers auto flow controller. Afc series auto 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, altemating current and direct current dual-purpose, flow manual control or automatic flow control and other merits. Afc series auto flow controller consists of impeller, 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, so the resolution ratio of regulation is relatively high. The application of advanced electronic technology provides the controller a high stability and anti-jamming ability.
