This reliable meter utilizes integrated optical sensor technology, ensuring highly precise measurement of extremely low gas and liquid flows, ranging from 1 g/h to 30 kg/h. As a standard feature, the flow meter includes an integrated PID controller, allowing for the creation of a compact flow control system when combined with a close-coupled pump or valve. The instrument also offers additional functionalities, such as alarms and counters, and boasts extensive connectivity options supporting RS232/RS485, Industrial Ethernet, or analog I/O for seamless integration into any system.
