The AW-Lake RT-30 is a rugged flow transmitter designed to provide a local rate and total display in demanding industrial environments where equipment is exposed to the elements . Housed in a NEMA 4X enclosure, it offers excellent protection against moisture and debris. Its integral swivel union allows the unit to be rotated 360° for optimal viewing, and it can be mounted directly on a flow meter or remotely when used with any AW-Lake frequency output sensor .

Programming the RT-30 is simple and safe, as key functions can be adjusted using the attached magnet without opening the enclosure. Flow rate or total can be displayed in a choice of engineering units. The transmitter accepts frequency inputs up to 4,500 Hz and features a powerful 30-point built-in linearizer to compensate for non-linear flow meter outputs, improving overall accuracy across the flow range .

The RT-30 provides versatile output options. It includes three opto-isolated open-collector outputs that can be programmed for frequency or limit outputs. An isolated 4-20 mA analog output, utilizing a 16-bit PWM converter, is also standard for integration with PLCs, recorders, or other control systems . Power is supplied by a customer-provided 9 to 24 VDC source .
