Paddle flowmeter DR05 series

volumefor liquidsDN50 - 2"

The DR05 paddle-wheel flow sensor measures the flow of water and substances similar to water. The flow sensor consists of a section of polypropylene pipe fitted with a paddle wheel. The paddle wheel, which extends into the area of flow, is set into rotation by the flowing liquid. The rotary motion is detected by a Hall sensor and output as a series of pulses. The output frequency of these pulses is directly proportional to the flow rate. Alternatively, the pulsed output can be converted into an analogue signal (4 to 20 mA) or into two limit contacts by optional integrated electronics. DR05 paddle-wheel flow sensors are made completely of plastic; they have no metal parts. These devices are available for pipe sizes of 1" to 2" with range ratio of up to 50:1. Typical applications Model DR05 paddle-wheel flow sensors are used wherever the flow of liquids having low viscosities must be reliably and economically measured, including but by no means limited to, the following cases: – in cooling systems – for demineralized water – for aggressive / caustic liquids in the chemical industry for low viscous liquids all plastic version without metallic parts materials: PP, ECTFE, Ceramic, Viton for pipe sizes from 1" to 2" NPT or BSP turndown ratio up to 50:1
