Feature:Flow range:1-60L/min, Water Pressure: 1.2MpaMonitor real-time flow rate and total flow numberControl quantitative flowYou can set the K constant for various flow meters.It is suitable for chemical (pharmaceutical), pharmaceutical, food, small and medium-sized pure water machines, quantitative (batch) management control of gas and liquid flows in industry.The LCD controller can monitor water flow, total flow, and control quantitative flow. When the flow reaches the set amount, you can reset the quantitative flow. The controller sends a signal to the valv-e, shuts off the water flow and automatically alarms. It is combined with pulse output flow sensor and solenoid valv-e to form a flow control system. It is suitable for chemical (pharmaceutical), pharmaceutical, food, small and medium-sized pure water machines, quantitative (batch) management control of gas and liquid flows in industry. Features:1. Light and thin design, flexible installation: suitable for assembly of various models, easy to use.2. the use of a large white backlight LCD screen: beautiful, generous, so that it is truly digital.3. the use of an ultra-wide range of external power supply: make it more widely used, more connected to a variety of models.4. It can realize the management and display of flow and quantitative (batch) of gas and liquid in various industries.5. temperature detection: can detect the temperature and display of each liquid.6. You can set the K constant for various flow meters.
