FLR1000 Series flow sensors are capable of measuring extremely low flowrates from 20 ml/min to 5 liters/min. These sensors are suitable for a wide variety of industrial, commercial and laboratory flow applications. FLR1000 series flow sensors operate on 12 Vdc or 24 Vdc power (depending on the model) and have been especially designed for incorporation into data acquisition systems that supply 12.5 Vdc to sensors and receive 0 to 5 Vdc linear signals from such sensors. Because of the low cost of these flow sensors, it is anticipated that these units will replace conventional glass tube and ball flow meters in many applications where an electrical signal proportional to flowrate is considered desirable. The FLR1000 Series uses a Pelton-type turbine wheel to determine the flowrate of the gas. Rotation rate of the turbine wheel is linear over a large dynamic range. The electro-optical system consists of a diode emitting energy in the infrared spectrum. Light energy is alternatively reflected and absorbed from “spokes” deposited upon the small turbine wheel. This reflected light energy is detected by means of a photo-diode. Thus, as the turbine wheel rotates in response to gas flowrate, electrical pulses are generated. Processing circuitry provides a dc voltage output proportional to the flow rate. For example, output signal is 1.0 Vdc at 20% of rated flow, 2.5 Vdc at 50% of rated flow, 4.0 Vdc at 80% of rated flow and 5.0 Vdc at 100% of rated flow. Sensors can handle 20% above their rated liquid flow without being damaged. The shaft and bearings will be damaged above the rated flow for gas units. Flow sensors are calibrated to air or water. Units are not recommended for gasses with a molecular weight less than 16. Please review wetted parts for chemical compatibility on applications which are not air or water.

Note: Units come with 0.9 m (3') cable and operator’s manual Note: Liquid flow sensors (Models FLR1007 through FLR1012) are available with brass instead of glass-filled polyphenelene; to order, add suffix “-BR” to model number and add $175 to price. All units are also available with pulse output in addition to 0-5 V output; add suffix “-P” and $50.
