Sierra 730-RFQ-1682-2 Flow Switch

The Sierra Instruments 730-RFQ-1682-2 Flow Transmitter is an inline flow sensor designed for direct mounting in a 1/2" NPT process line to monitor and report flow in industrial systems. It operates with a 15 VDC control input and is rated for pressures up to 80 psig, enabling compact installations in low- to moderate-pressure applications. Weighing approximately 0.41 kg, the unit is built for rugged use in demanding environments and is compatible with standard wiring in field or panel installations. The model number 730-RFQ-1682-2 identifies this specific inline flow transmitter within Sierra’s 730-series family, providing a compact, reliable solution for flow detection and measurement in automated process schemes where space and power constraints are factors. This device is suited to applications requiring a small-footprint flow transmitter with a fixed 1/2" NPT connection and a 15 VDC control interface, making it a practical choice for inline flow monitoring in gas or liquid handling systems and other process pipelines.
