The Brooks® Ar-MiteTM is a reliable, low flow metal tube flowmeter with |
||||||||
|
316L stainless steel wetted parts. The magnetically coupled indicator |
||||||||
|
provides a highly reliable method of indication. This model is a practical |
||||||||
|
and economical approach to low flow rate indication for high pressure and |
||||||||
|
difficult to handle fluids. Optional accessories include 4-20 mA output, |
||||||||
|
Needle Valve, Flow Controllers and Alarms. |

1-3 Optional Equipment |
|
|
|
Standard Needle Valves
The standard needle or cartridge valves can be supplied integrally mounted to the inlet fitting of the instrument. The optional NRSTM needle valve, also integrally mounted to the inlet fitting, provides a greater number of turns affording precision control. For more details on the needle or cartridge valves go to our website: BrooksInstrument.com,
select Documentation,Precision Valves and Flow Controllers, Brooks-Line IVTM, CART valves or NRS valves.
Limit Switches Inductive Alarm Switch
One or two electronic limit switches type SJ2-N can be installed in the indicator housing to allow initiation of signaling or switching functions on a preset flow value being reached. The SJ2-N limit switch operates as a slot initiator that is inductively actuated by a cam mounted to the pointer. Any flow value can be used for setting the limit value by sliding the switch along the slot in the mounting plate for the initiators. Minimum setting distance between two limit switches is approximately 50% of the scale range. (Refer to Figure 1-1)

Figure 1-2 Reed Switch Wiring Diagram
Reed Switch Alarm
Two reed switches are installed in the alarm housing to provide signaling or switching functions when a preset flow value has been reached. The reed switches provide high, low or dual setpoints and latched output over the full range. The switches are normally adjusted to the desired flow range in the factory. Modifications to the switch settings can be made in the field, refer to Section 3-4. Minimum setting distance between two switches is approximately 40% of the scale. (Refer to Figures 1-2 and 1-3)

Figure 1-3 Model MT3750C with Reed Switch Alarm
Transmitter: 3750
The transmitter provides accurate magnet angle detection and conversion to a 4 - 20 mA industry standard output signal, based on the position of a float assembly in the flowmeter. This rugged, compact, microprocessordriven device is capable of providing accurate flow information to your external support systems. The patented magnetic sensor with automatic gain control enables an extremely high dynamic capture range without sacrificing accuracy. (Refer to Figures 1-1, 1-4 and 1-5)
