NT® Electronic Flowmeter Model 4400
● Provides simultaneous measurement of outlet pressure and flow rate.
● Ideal for capturing critical diagnostic information for monitoring or controlling process applications such as chemical, DI water and slurry dispense, precision blending and metering and totalized flow for custody transfer.
● No moving parts reduce particle generation potential.
● Nonmetallic sensing technology provides reliable measurement.
● Integral pressure transducer provides additional process information.
● The flow-through design minimizes dead volume, reducing contamination potential.
● PTFE, PFA, CTFE, and Kalrez® wetted surfaces for high-purity applications.
● Industry standard Flaretek® flared port connections reduce entrapment areas, minimize footprint, provide system design flexibility and simplify installation.
● 100% functionally tested prior to shipment. Performance is calibrated for an accuracy of 1% of full scale.
