The Brooks electric electronic equipment bearing the CE mark has been successfully tested to the regulations of the Electro Magnetic Compatibility EMC directive 89 336 EEC Special attention is required when selecting the signal cable to be used with CE marked equipment To provide for optimum system performances the following guidelines should be observed 1 Before use confirm the fluid to be used is compatible with the meter 2 The flowmeter must be installed so the shafts of the rotors are horizon tal never vertical or on end Severe damage to components may be the result See Figure 2 1 A 200 mesh strainer should be installed upstream and adjacent to the flowmeter to protect it from foreign matter 003 075mm Maximum such as dirt pipe scale or welding splatter See Figures 2 3 and 2 4 ACAUTION It is important to provide a strainer and to properly maintain it Failure to do so can result in particles causing the rotors to jam and resulting in blocked fuel flow which can create a hazardous condition such as engine failure when installed on motor vehicle 4 Valves should be installed to facilitate removal of the flowmeter and strainer See Figures 2 3 and 2 4 Install the flowmeter on the discharge side of a pump whenever pos sible Before installing the flowmeter wash and clean the inside of the pipeline with compressed air or steam This is particularly important on new

10. The flowmeter has been completely assembled checked and calibrated at the factory Therefore no adjustments are required for installation 3 2 Flowmeter Principle of Operation See Figure 3 1 The Oval Flowmeter accurately measures liquid flow by using a slight pressure differential to rotate a pair of oval gears The meshed gears seal the inlet from the outlet flow developing the pressure differential When in the position as shown in Figure 3 1A Gear A receives torque from the pressure difference the torque upon Gear B cancel one another and Gear Adrives Gear B as depicted in Figure 3 1B When Gear A rotates to the position as shown in Figure 3 1C it loses torque but Gear B obtains torque and drives Gear A This alternate driving action provides a smooth rotation of almost constant torque without dead spots Figures 3 1D 3 1E 3 1F 3 1G 3 1H and 3 1J illustrate this principle through a complete cycle bringing Gear A back to its original position as shown in Figure 3 1A During rotor rotation the rotors trap precise quantities of liquid in the crescent shaped gaps or measuring chambers Total quantity of flow for one complete cycle of the rotors is four times that of the crescent shaped gap Rate of flow is proportional to the rotation speed of the rotors Because the amount of slippage between the rotors and the measurement chamber wall is minimal the flowmeter is essentially unaffected by changes in viscosity and lubricity of the li
