NALL Series Mass Flow Meter-Image

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.
