Dwyer RTI2 Series Flow Rate/Total Indicator some models are designed for any pump, pressure, or gravity feed system. The Series RTI2 Flow Rate/Total Indicator is an indicator/transmitter that takes the pulse output signal from compatible flowmeters, displays flow rate and total, and provides output signals.

Flow Switches come as paddle, thermal, piezo, and shuttle/piston. Flow meters indicate flow rate. The different sensors include dial, in-line, ultrasonic, orifice plate, totalizing meters, variable area, venturi, or with switch output. The different designs of the flow meters have a variety of applications.

Flow sensors with flow totalizing capability. Models contain LCD displays. Ideal for industrial use in reverse osmosis water purifying systems. Applications include water treatment, cooling systems, irrigation and water utilities.

Dwyer RTI2 Series Features

  • Can be mounted on a wall or mounted on the flow meter for added flexibility
  • Accessory mounting kits make it easy to change the mounting orientation
  • High environmental protection with semi-flexible urethane potted electrical components
  • Provides a pulse, 4 to 20 mA, and dual-relay output


  • Water treatment
