NALL SERIES Transducer Dimensions TELEDYNE HASTINGS NALL-SERIES MASS FLOWMETERS INSTRUMENTS Model NALL FEATURES • The Original Hastings Mass Flowmeter • 15 Standard Flow Ranges • No Corrections for 20% Variations in Temperature or Pressure H Series Transducer DESIGN FEATURES The Hastings NALL-Series Flowmeter is the original model that has generated repeat customers for over 50 years. It operates on a unique thermal principle which permits inherently linear response to flow. The flow passage is constructed entirely of metal and contains no O-rings. The transducer is also separate from any electronic circuitry, making it ideal for high temperature or other adverse environmental applications. The power supply features a bright digital display and is contained in either a cabinet or panel mountable case. All models feature high accuracy and excellent repeatability. For All of Your Gas Flow Measuring Needs: • Vapor Deposition • Leak Testing • Gas Blending • Semiconductor Processes • Measurement of Toxic and Hazardous Gases • High Temperature, High Pressure, and Hermetically Sealed Uses Model NALL Power Supply Your Customer Service Representative TELEDYNE INSTRUMENTS Hastings Instruments A Teledyne Technologies Company PB 155-5/03 © Teledyne 2003.
