Fire flange ultrasonic flowmeter is a flow measurement device specially designed for fire water system. It is usually installed on pipelines using flange connection to ensure stable and reliable measurement under high pressure and emergency situations. It can be used for fire water supply pipelines, indoor and outdoor fire hydrant systems, and can also be connected to plastic pipes such as HDPE water supply pipe and PVC water supply pipe. This flowmeter is suitable for various liquid media, including fire water, and can provide high-precision flow data, which is crucial for ensuring the water flow of the fire protection system.
Which valves should be used in conjunction with
1. Gate valve: In the fire water supply system, buried pipeline valves are usually recommended to use non rising stem gate valve with opening and closing scales, while corrosion-resistant rising stem gate valves can be used in valve wells. Gate valves are used to control the opening and closing of water flow, and when used in conjunction with ultrasonic flow meters, can accurately control and measure flow.
2. Butterfly valve: In the selection of valves for indoor and outdoor overhead pipelines, butterfly valves are recommended for their easy operation. They can be used in conjunction with ultrasonic flow meters to control and measure water flow in firefighting pipelines.
3. Check valve: The check valve on the outlet pipe of the fire pump should use a water hammer elimination check valve to prevent water hammer effect. When the water supply height exceeds 24 meters, a water hammer eliminator should be used. Check valves ensure one-way flow of water, prevent backflow, and work together with ultrasonic flow meters to ensure measurement accuracy.
4. Pressure reducing valve: The pressure reducing valve should be installed before the inlet of the alarm valve group, and a filter should be installed at its inlet. Pressure gauges should be installed before and after the filter and pressure reducing valve, and control valves should be installed before and after the filter and pressure reducing valve. The pressure reducing valve is used to reduce the water flow pressure to the required level of the system, and is used in conjunction with an ultrasonic flowmeter to monitor the flow rate after pressure reduction.
