Piston flow controller is equipped with an internal measuring pipe fitted with a permanent magnet of the piston, the piston when the pressure difference caused by the flow pushes the thermal conductivity flow switches, magnetic piston will be driven by a magnetic seal inside the device is switched action. Diameter piston determines the start traffic. When the sky i, stainless steel springs will push the piston reset. Pornographic films after the switch is actuated, the alarm can be remote or direct flow switch principle, used for liquid or gaseous media. Sturdy plastic flow switch type, aluminum or stainless steel housing options. Liquid flow switch is used to measure liquid flow through the pipeline state, for example: water, ethylene glycol, or any of brass, phosphor bronze and corrosion-free is not as hazardous liquid fluid, the typical application is the use in You need a chain reaction or 'disconnection' of protected sites. 1, flow switches are widely used in air conditioning, refrigeration and other occasions require water protection. 2, micro-switches using Omron products. 3, for the measurement of liquid flow through the pipeline state. Flow switch type, swim grace (certified), flow switch provided by the Beijing Amusement TU Technology Limited. Beijing Tour En Technology Co., Ltd. (www.bjyouen.com) (www.bjyouen.com) is the Beijing Haidian District, chemical instrumentation leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum meet customer needs. Well leader in travel with the staff warmly welcome all inquiries negotiations to create a better future tour grace.
