the Flowmeter is specifically rated for higher pressures), applying a diluted soap solution to the flow 
connections, and monitoring the connections for bubbles of escaping gas. 

 

Electrical Connections 

If a power supply from Hastings Instruments is used with a ±15 Volt version of the HFM-201/205, HFC- 
203/207, installation consists of connecting the appropriate cable (#AF-

8AM) from the “D”

 

connector on the rear of the power supply to the “D” connector on the top of the flow 

instrument. If a 

different power supply is used, use the following instructions when connecting the flowmeter or controller.

 

 

WARNING:

 Care must be taken to avoid any high voltages that may be present when dealing 

with power supplies.  To prevent the spread of fires in the event of a fault, only use power 
supplies power limited to no more than 150 VA.  Hastings power supplies meet this 
requirement.  The available current for each 200 series instrument connected to a power 
supply should not exceed 1.6 A. 

2.5.1. 

Bipolar (±15 VDC) Power Supply to Bipolar Connections 

Connecting the HFM-201/205, HFC-203/207 series flow instruments with anything other than the prescribed 
cables and power supplies discussed above, can severely damage the instrument and void the warranty. The 
figure below shows the schematic layout for connecting the instrument to an appropriate ±15 Volt power 
supply. A pinout is also given to show the signals available to the user and the signals given and used by the 
power supply (Not all signals from the pcb are used by Hastings supplies). 

 

The power supply used must be meet the power requirements delineated in the specifications. If a bipolar 
supply is required, the voltages must be referenced to a common ground. Connect -15 VDC to pin 9 of the 
DA-15 connector and +15 VDC to pin 11. Pins 5 and 12 are both commons and they must be connected 
together and to the ground connection at the power supply. Do not connect them together at the flow 
controller as the resulting crosstalk could result in flow instabilities.
