Accurate flow measurements are critical to good process monitoring and control in many plants. Fit-for-purpose flow switches can help improve process control, reduce plant downtime and maintain safe operations.
Save time and have confidence in your flow measurements by selecting and installing the right flow switches. Explore our extensive catalogue or talk to our expert technical support team for personalised support on specifying the right flow solutions for your specific process and plant conditions.
Flow switches can be used to perform various functions such as monitoring fluid flow rates through system processes, triggering an alarm on detection of high or low flow, or even activating plant or equipment trips.
The term flow switch usually refers to devices that initiate actions (such as starting or stopping other processes within a system) upon detecting deviations in flow from predefined parameters. A sensor that measures, registers and displays information is more commonly known as a flowmeter or flow indicator.
Flow switches are usually activated through paddle or magnetic triggers that become displaced when a liquid or gas passes through. A signal is then sent to a transmitter via a transducer to output a flow reading. The transmitter compares the reading against set parameters and depending on system requirements, the transmitter can initiate further signals for other process actions. These actions can include automatic shutdowns for pump or system protection, alarms for operator investigation or start-ups of other plant processes.
