Description

FLR1000 Series flow sensors can measure extremely low flow rates from 20 mL/min to 500 L/min. These sensors are suitable for a wide variety of industrial, commercial, and laboratory flow applications. FLR1000 Series flow sensors operate on 12 Vdc power and are designed for incorporation into data acquisition systems that supply 12.5 Vdc to sensors and receive 0 to 5 Vdc linear signals in return. Because of their cost effectiveness, FLR1000 Series units may replace conventional glass tube and ball flowmeters in applications in which an electrical signal proportional to flow rate is desired.

The FLR1000 Series uses a Pelton-type turbine wheel to determine the flow rate of the gas. The rotation rate of the turbine wheel is linear over a wide 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 on the small turbine wheel. This reflected light energy is detected by a photodiode. Thus, as the turbine wheel rotates in response to gas flow rate, 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 flow without being damaged.

For liquid flow metering with integrated rate display, the FLR1000ST-D Series has been setting the pace. Their advanced Pelton-turbine design provides high turndown ratios, fast response, and repeatable accuracy. A 0 to 5 Vdc analog output is standard. Featuring a 3½-digit display of flow rate in engineering units, these flowmeters are perfect for any laboratory or test facility. For higher-pressure applications or where metal may be required, the FLR1000ST Series is the solution.

Designed for applications where stainless steel may be required, the FLR1000ST Series flowmeters are rated to 500 psig. These units are available to cover flow ranges from 13 mL/min to 10 L/min. A 0 to 5 Vdc or 4 to 20 mA analog output is standard with all units; Voltage output models are also available with an additional pulse output, or with a 3½ digit LCD readout.
