Sage Prime® is our most popular Gas Thermal Mass Flow Meter preferred by our Industrial, Environmental and Commercial customers for many gas flow applications. It is packaged in a robust, yet lightweight, dual-sided NEMA 4 enclosure, is CE compliant, and meets UL and CSA standards for hazardous service. Easy access to a separate rear compartment with large, well marked terminals provide ease of customer wiring. Provides isolated 4-20mA and pulsed output along with Modbus® compliant RS485 communications, HART optional. It features a bright, high contrast graphical display reporting Flow Rate, Total and Temperature and even provides the raw calibration milliwatts (mw) for diagnostics which is the key to our popular, money saving, In-Situ Calibration Check.
