and fusl consumption rnsasurarrisni!! Applying our proprietary precision rotors, this flowmeter measures the process flow at a high degree of accuracy as a servo mechanism continually controls the rotor rotation to maintain "zero differential pressure" across the inlet and outlet at all times. Ideal for measuring of injection quantity into engines, injection nozzle flowrate, microflows at laboratories and test plants, or precisely controlled additives in very small quantities. Typical Applications Injection volume measurement in gasoline injectors Fuel consumption measurement on the engine test bench Assessment of materials for bioethanol Oval ; taking on extra-lowflow measuring OVAL Corporation
Open the catalog to page 1General Specifications Sensor (basic fowmeter) [Operating Principle] As the fluid flows across the meter, a pressure differential is created between the inlet and outlet of rotors. The resultant pressure differential moves a free piston incorporated in the capillary line in the bypass. A photodiode sensor keeps track of the position of free piston and feeds back the obtained position information, via the controller, to the servomotor. It thus serves to maintain the pressure differential between the inlet and output of rotors at zero continuously. By maintaining the pressure differential at...

Compared with the traditional direct shaft coupling, its benefits include desirable sealing performance, long life and consis- tent accuracy particularly in low flow ranges. @ Measuring unit: Rotors are accommodated in a cartridge type measuring unit for maximum ease of rotor replacement. In the event of rotors jammed with foreign solids, you can promptly replace them in the field and resume operation in the line after you enter parameter "meter...
