Page 5: General Information
1.0 GENERAL INFORMATION 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. Hastings Mass Flowmeters do not require any periodic maintenance under normal operating conditions with clean gases.

Page 7: Installation And Operation
2.0 INSTALLATION AND OPERATION 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: 2.1 Receiving Inspection: 2.1 Receiving Inspection: 2.1 Receiving Inspection: 2.1 Receiving Inspection:...
Page 8: Electrical Connections
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.
Page 9: Theory Of Operation
3.0 THEORY OF OPERATION 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 6.0. In this section and other sections throughout this manual, when a power supply is mentioned, it is assumed that the customer has a Hastings Power Supply.
Page 10: Electronics
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.
Page 11 The HFM-230 uses a shunt which is a corrugated and fused shunt similar to the shunt used in the lower flow range instruments (see Figure 3.7). This highest range shunt is adjustable from 0- 50 slpm to 0-500 slpm. The HFM-229B Series uses an external laminar flow element instead of an internal shunt, because the necessary size for the element exceeds the body size of the flowmeter.

4.0 MAINTENANCE 4.1 Introduction: 4.1 Introduction: 4.1 Introduction: 4.1 Introduction: 4.1 Introduction: This section contains service and calibration information. Some portions of the instrument are delicate. Use extreme care when servicing the flowmeter. The potentiometer positions and the electrical compo- nents referred to in the troubleshooting section can be found in Section 6.0 on the electrical component layout drawing.

End Cap Removal End Cap Removal End Cap Removal End Cap Removal End Cap Removal The end cap on the inlet side must be removed to gain access to the filter or shunt assembly. First shut off the supply of gas to the instrument. Disconnect the Swagelok fitting on the inlet and outlet sides of the instrument.

5.0 REPLACEMENT PARTS The following is a list of the available replacement parts and their factory stock numbers. The HFM- 229, HFM-229B, HFM-200, HFM-200B, and the HFC-202 shunts and filter discs are interchange- able. The HFM-230, HFM-201, and the HFC-203 shunts and filter discs are also interchangeable. The same sensor module is used on all of the above models.
