NT® High-Temperature Flowmeter Model 4401
● Can handle up to 180°C (356°F) process chemical temperature.
● No moving parts to generate particles.
● Nonmetallic sensing technology for reliable measurement.
● Pressure output included – eliminates need for additional instruments.
● Easy installation in any orientation.
● PTFE, PFA, CTFE, and Kalrez® wetted surfaces for high-purity applications.
● 100% functionally tested prior to shipment. Performance is calibrated for an accuracy of 1% of full scale.
