Mass Flow 3440 SERIES 3300 SERIES 3660 SERIES 3200 SERIES 3660NV SERIES Small Karman vortex flow meter for liquids 3810S SERIES 5400 SERIES 8100 SERIES REEDOUT_UNIT CR500 Standard Mass Flowmeter MODEL 3660NV SERIES MODEL 3660NV Series is the compact and low-cost mass-flowmeter that has been developed based on MODEL 3660 series. They has been developed as a successor to the MODEL 3750 series that has achieved many satisfactory results as a standard-adopted machine for various analysis devices and vacuum devices in applications of research and development in a number of universities and laboratories. Features Installation of the flow sensor of an improved constant-current temperature-difference detection type enables high-speed responses to be realized. It is possible to install it anywhere because of its compact body. Combination with DPM-100 enables alarm to be output (flow monitoring). Combination with CR-500 enables flows to be accumulated (consumption monitoring). Standard specifications Flow range (on N2 conversion basis) F.S. 50 to 500 SCCM, 1 to 20 SLM Response 2 sec. or less (typical) Accuracy within ± 1.5% F.S.
