The SMC ATMF-PRISM is a portable thermal dispersion flowmeter, utilizing the constant temperature difference method of measuring gas mass flow rate. The SMC PrismTM is the newest innovation in our product line, providing a portable battery operated thermal mass meter with extensive data logging capability. Designed to operate for up to 10 hours on a built-in rechargeable Lithium-ion battery, the insertion style portable ATMF-PRISM can measure and log gas flows through existing ports in pipes 2″ and larger. The ergonomically designed Prism Portable can log in LOGGING Mode or MANUAL LOGGING Mode. AUTO Mode will capture a flow data point every 10 seconds. MANUAL Mode will capture a Flow data point each time the SEL button is pressed and the display will flash as each point is captured. The data is stored in the portable unit for subsequent transferring to a file, and also displays the data visually. The ATMF-PRISM comes with software, an addresser, as well as an interconnect cable to handle all data transfers between the portable unit and a computer. The cable connection is made via a Mini-USB port. The ATMF Prism can be set up for up to 16 different calibrations or applications.
