Electronics Options
Each Rheotherm flow meter consists of one of our sensors with one of a number of available electronics configurations. The best choice of electronics depends on the application parameters and other options you may need; Contact Us for help in selecting the most appropriate unit for you. The available electronics choices are:
210 – This is our most frequently recommended unit for common applications. The Model 210 is a linear meter with the electronics and sensor integrated into one unit. Another version (210R) is also available with the electronics separate from the sensor. Click for more information about the Model 210 (product brochure).
213 – For measuring bi-directional flow of liquids or gases. Another version (213R) is also available with the electronics separate from the sensor.
111D – linear electronics; up to 20:1 turndown
112 – linear electronics; up to 100:1 turndown
100 – nonlinear electronics (output approximately a logarithmic function)
400 – Flow indicator – low cost method of determining the existence and magnitude of flow.
100CS – flow switch with single relay output (SPDT), field-adjustable setpoint
100FS – flow switch with electronics separate from sensor to accommodate additional output options
