Page 41: Optional 4-20 Ma Current Output
1.4. Optional 4-20 mA Current Output An option to the standard 0 - 5 VDC output is the 4 - 20 mA current output that is proportional to flow. The 4 - 20 mA signal is produced from the 0 - 5 VDC output of the flow meter. The current loop output is useful for remote applications where pickup noise could substantially affect the stability of the voltage output or long cable runs where cable resistance would cause a voltage signal to decay. -
Page 42: Interconnecting Cables
1.5.2. Interconnecting Cables Cables are available from Hastings, in various lengths, to connect from the 15 pin "D" connector on the back of the Power Pod directly to any of the 200 series and 300 series flow instruments (including digital versions). -
Page 43: Installation And Operation
2. Installation and Operation This section contains the steps necessary to install a new flow meter/controller into operation as quickly and easily as possible. Please read the following thoroughly before attempting to install the instrument. 2.1.

EXAMPLE: Suppose a 4” LFE is selected. The length of 4” diameter tubing or pipe, upstream of the sensor inlet tap, will be a minimum of 20“. The minimum length of 4” tubing or pipe downstream from the sensor outlet tap will be 4”. The length of additional 4” inlet tubing required for the 4”... -
Page 46: Operation
24 Volt Connections Refer to the diagram to the right when connecting 24 Volt units. Connect the positive lead of the power supply to pin 7 of the DE-9 connector and negative lead to pin 4. The supply input is diode protected such that reversing the input polarity will not damage the instrument. -
Page 47: Zero Check
2.6.2. Zero Check Turn the power supply on if not already energized. Allow for a 1 hour warm-up. Stop all flow through the instrument and wait 2 minutes. Caution: Do not assume that all metering valves completely shut off the flow. Even a slight leakage will cause an indication on the meter and an apparent zero shift. For the standard 0 - 5 VDC output, adjust the zero potentiometer located on the lower outlet side of the flow meter until the meter indicates zero. -

Page 49: Operation With An External Sensor (Fig. 2.2)
2.7.3. Operation with an external sensor (Fig. 2.2) In some instances, it might be desirable to use an external Fig 2.2 sensor to provide process information to the control circuitry in the flow controller. For example, you might want to control the pressure in a vacuum system by adjusting the rate at which the system is backfilled with a gas. -
Page 50: Range Changing
controller circuit establishes control at the new command point. This jumper does not affect the system gain and will not dampen out oscillations. To adjust the response, you need a means of producing a step change in the command voltage from 10% of full scale to 100% of full scale. -
Page 51: Theory Of Operation
3. Theory of Operation This section contains a functional description of Hastings flow controllers. Detailed schematics and parts lists can be obtained by contacting Hastings using the contact information found at the end of this document. 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 52: Electronics
relatively constant over wide ranges of temperature and pressure, the flow meter may be calibrated directly in mass units for those gases. Changes in gas composition usually only require application of a simple multiplier to the air calibration to account for the difference in heat capacity and thus the flow meter is capable of measuring a wide variety of gases. -
Page 53: Valve
3.5. Valve The control valve is an “automatic metering solenoid” valve. While most solenoids operate in either the fully open or fully closed state, the automatic metering solenoid valve is designed to control flow (see Figure 3.5). A spring, connected to the plunger assembly, holds a magnetic plunger tightly against an orifice to shut off flow. -
Page 54: Maintenance
4. Maintenance This section contains service and calibration information. Some portions of the instrument are delicate. Use extreme care when servicing the flow controller. 4.1. Authorized Maintenance With proper care in installation and use, the flow controller will require little or no maintenance. If maintenance does become necessary, most of the instrument can be cleaned or repaired in the field. -
Page 55: Adjustments
CAUSE: Plugged orifice. ACTION: Verify the presence of a 10-50 psig pressure across the instrument. If present, shut off gas supply and power supply. Remove orifice per Section 4.9. Examine orifice. If plugged, clean or replace as applicable. Reassemble valve. SYMPTOM: Flow meter reads other than 0.00 VDC with no flow, or there is a small flow when flow meter reads 0.00 VDC. -
Page 56: Miscellaneous Adjustments
4.3.2. Miscellaneous adjustments Periodically, during normal operation, the ZERO should be checked and adjusted when required. If the instrument is not shutting completely off when the Valve Override CLOSE function is active, or a command of zero flow has been given, then the orifice may require approximately 1/8 turn clockwise. 4.4. -
Page 57: Hfc-202 Orifice
B) If P >2P , use formula 1; otherwise use formula 2. C) Use a consistent set of units for pressure, flow, and density (i.e all lengths, masses, times in the same units, cm, ft, kg, sec etc.) 1 liter/minute = 1.667 x 10 /sec, 1 gm/liter = 1 kg/m , 1 psia = 6895 kg/m*sec... - Page 58 Lubricate the O-rings slightly with a silicone based grease, and the threads with anti-galling compound. Push the orifice into its hole and screw it in until it is flush with the instrument base. Apply pressure to the inlet side of the instrument. Enable the Valve Override CLOSE function or unplug the instrument.
