126B - PAGE 5 1.0 GENERAL INFORMA TION Hastings 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.

126B - PAGE 7 2.0 INST ALLA TION AND OPERA TION This section is designed to assist in getting a new flowmeter into operation as quickly and easily as possible. Please read the following thoroughly before attempting to install the instrument. 2.1 Receiving Inspection: 2.
126B - PAGE 8 The standard inlet and outlet fittings for the HFM-229B Flowmeter are NPT thread in the size of the pipe listed on the drawing on page 22, for sizes up to 3" laminar. On the 4", 6", and 8" laminars, flange fittings are standard.
126B - PAGE 9 3.0 THEOR Y OF OPERA TION This section contains an overall functional description of Model HFM Flowmeters. Detailed schematics and parts lists can be found at the end of the manual in Section 6.
126B - PAGE 10 For a constant power input, the differential thermocouple output is a function of the mass flow rate and the heat capacity of the gas. Since the heat capacity of many gases is relatively constant over wide ranges of temperature and pressure, the flowmeter may be calibrated directly in mass units for those gases.
126B - PAGE 11 The HFM-230 uses a shunt which is a corrugated and fused shunt similar to the shunt used in the low er flo w range instruments (see Figure 3.
