 CX-D2(D4,D20) Super Micro Flow Meter

Principle and Design

The measuring device consists of a double ring swinging piston which produces oscillating rotary and swinging motion due to alternating filing and emptying the measuring chambers. Thanks to a small weight of the pendulum and the minimum losses arising from friction the flow meter CX-D2(D4,D20) reacts even to the smallest volume flows. At a constant flow, the cycle described above is repeated proportionally to the flow approx. 5 to 300 times per one second. In the process, for each one cyclic revolution a volume of approx. 0.02 cm³ is pressed out and thereby one pulse. In addition, the piston design minimizes losses due to leakage and this guarantees good linearity and repeatability of the measured values. A suitable frequency-and pickup system records oscillation motions in a contactless manner through the body wall and transmits output signals at a frequency which is proportional to the volumetric flow. The flow meter CX-D2(D4,D20) 10 is compact and its weight. This flow meter is made of stainless steel, In order to achieve a faultless operation it is recommended to equip the flow meter CX-D2(D4,D20) with a filter of aperture size < 40µm.

Application
The flow meter CX-D2(D4,D20) is designed for low-viscosity fluids of all types, especially for use in dosing and filing devices. It is designed for low volume flows from 0.0003 l/min. and shall be applied wherever small amounts of additives are dosed or injected. Due to having large resolution it is guaranteed optimal dosing accuracy even in case of the smallest liquid volumes. The values of self-pulsing flows are reproducible with the repeated accuracy of +/- 0.1%. Due to its small compact design the CX-D2(D4,D20) may be used without problems even in a very confined space for installation
