1.0 General Information

1.1Features:

Hastings Linear Mass Flowmeters are designed to accurately measure mass flow without corrections or compensations for gas pressure and temperature. Due to a linear electrical output signal, the flowmeters are ideal for use with totalizers and recorders. Hastings Linear Mass Flowmeters do not require any periodic maintenance under normal operating conditions with clean gases. No damage will occur from the use of moderate overpressures, overflows, or liquid solvents.

The standard flowmeter calibration is for air. Special calibrations for most other gases such as oxygen, nitrogen, hydrogen, and carbon monoxide, are available on special order, or by use of a gas multiplier. Special calibrations are noted by the following options such as OPT-G (special gas) or OPT-R (special range) and OPT-GR (special gas and range).

Standard HS-Series transducer and L-Series laminar flow elements are available with 300 Series stainless steel or monel construction. U-Series low pressure drop transducers are constructed of monel.

The basic flowmeter is available in either a cabinet model or a NIM panel. The NIM model can be mounted side by side in groups of three, in an optional NIM frame. Chassis models are available on special order.
