WebA riser check valve utilizes a vane type water flow switch to monitor water flow in the sprinkler system. When a con-tinuous flow of water — more than 10 gallons per minute — occurs, a standard check valve or a water flow switch mon-itors the system and activates an alarm after a predetermined amount of time. WebThe flow and differential pressure switches (discussed in the sensor sections and an example shown in Figure 4-41 (Kele, 2002) tend to be problematic in practice, particularly on fan systems due to sensitive set points and failures of paddles over time, however they are still widely used to sense filter status, and air flow proving for electric heaters.
