The AW-Lake RT-30EX flow transmitter is ideal for any industry or flow measurement application where an explosion-proof local rate and total display is required, such as in offshore chemical injection, hydraulic fracturing, or industrial paint spray booths. The NEMA 4X enclosure provides environmental protection from moisture and debris. Flow rate or total can be easily programmed to display in a choice of engineering units. Simply use the magnet that is attached to change any key functions; opening the enclosure is not required .

The AW-Lake RT-30EX flow transmitter features easy thread-in installation. A quick setup procedure allows you to have the flow monitor working with just a few simple programming steps. The RT-30 can be mounted remotely when used in conjunction with any AW-Lake frequency output sensor. Because of the integral swivel union, the RT-30 unit can be rotated 360° for optimal viewing from any angle .

Technical specifications include 0 to 4,500 Hz frequency range, 30-point built-in linearization for improved accuracy, and 3/4 inch female NPT conduit connection. Input includes one opto-isolated input for 9 to 24 VDC remote reset. Outputs include three opto-isolated open-collector outputs programmable for frequency or limit outputs (5 to 30 VDC, 40 mA max) and a 4-20mA analog output (PWM converter, 3 or 2 wire plus separate supply, 500 ohm max load) .

Power requirement is 9 to 24 VDC / 200mA, Class 2 (customer supplied). Operating temperature range is -4 to 140°F (-20 to 60°C). CSA Certifications include Class I, Div. I, Groups C, D; Class II, Div. I, Groups E, F, G; and Class III .
