2 2 Description Oval gear flowmeters are categorized as positive displacement flow technology. When liquid flows through this type of positive displacement flowmeter, two oval geared rotors measure a constant volume per rotation in a precisely machined measuring chamber. With each rotation, a constant volume of liquid is measured. The rotation of the oval gears is sensed via magnets embedded in the rotors. These magnets transmit a high resolution pulse output. The output signal can be processed externally via a remote display controller or PL or via a variety of output/display options available as accessories attached to the flowmeters. Operation: Liquid travels around the crescent shaped chambers created by the rotational movement Liquid in transit of the rotors Liquid entering the measuring chamber Flow Liquid exits the measuring chamber The positive displacement flow technology allows for precise flow measurement of most clean liquids regardless of the media's conductivity. Other liquid properties also have a minimal effect on the performance of this type of meter. Flow profile conditioning is not required, as alternative flow technology options, making oval gear installations simple to install in tight spaces and at a economical price. reas of pplication Suitable for viscous, non abrasive, clean liquids like: Petroleum Oil hemicals Grease Fuels Ink Pastes In addition to lubricating media, stainless steel flowmeters are suitable for most products and chemicals.

Recommended Filter DON-x05... DON-x15: < 75 μm micron (200 mesh) DON-x20: < 150 μm micron (100 mesh) Reed Switch Pulse Output (.. R0) The reed switch output is a two wire normally open SPST voltage free contact ideal for installations out power or for use in hazardous area locations when Intrinsically Safe (I.S.) philosophy is adopted. Note: When using the reed switch output the liquid tem perature must not change at a rate greater than 18 ºF /min. verage switching life of reed contact (MTTF): Max. Load (100 V / 10 m) 5 x 10 5 switching cycles Min. Load (<5 V / 10 m) 5 x 10 8 switching cycles Power Supply: max. 30 V D, max. 200 m Hall Sensor Pulse Output (.. H0) In the electronics options H0, a Hall Effect sensor is combined an active push-pull output. The electrical connection is provided in 3-wire version. The output is actively switched either to +Vs or to ground. The external supply voltage is V D. No additional external circuit is required (e.g pull up resistor). The high signal is approximately equal to the supply voltage +Vs and the low signal is approximately 0 V. The electrical load may optionally be connected to the supply voltage or to GND. Maximum output current (current source or sink): 100 m (short circuit protected). In addition to a Hall sensor, this option is equipped a Reed switch which works the same as Option R0.

Special cut rotors, option "Y" have alternate tooth relief which effectively reduces the pressure drop by 50%. When sizing a meter, be sure your selection falls below the 1 bar (14.5 PSI) maximum allowable pressure drop line on the graph. 4

This option applies to DON-H15 and larger sizes. For higher viscosities, the flowmeter max. flowrate is derated according to the table above. Example: DON-H20 measuring viscous oil at 8000 cp: max. flow of 40 GPM x 0.5 = 20.0 GPM new max. flow rate.
