Brooks Instrument Section 2 Installation Transit Precautions To safeguard against damage during transit, transport the instrument to the installation site in the same container used for transportation from the factory if circumstances permit. Fluid Connections General Mounting Practices Use good piping practices to minimize transmitting any torque or bending loads onto the process connections on Quantim . Always verify there are no leaks prior to starting Quantim... - Page 16 Brooks Instrument Section 2 Installation Recommended installation procedures: a. All models should be mounted to a stable surface that is relatively free from mechanical shocks and mechanical vibration using the supplied mounting plate. b. Leave sufficient room for access to the electrical connections. c. Install in a manner that allows the instrument to be easily removed. d. Install the instrument with an appropriate filter on the fluid inlet side. e. It is recommended that a positive shutoff valve be installed downstream of the Quantim ® to allow for proper zeroing after installation. CAUTION The control valve of the Quantim Mass Flow Controller provides precision control and is not designed for positive shutoff. If...

Page 17: Process Mounting
Brooks Instrument Section 2 Installation Process Mounting Quantim will function in any orientation if the Coriolis sensor and the control valve remain filled ® with process fluid. Entrapped gas in a liquid application and entrapped liquid in a gas application should be prevented as it may disturb the Coriolis sensor and the control valve. Install Quantim ® considering the direction of the FLOW arrow. The arrow indicating proper flow direction is engraved on the instrument between the process fittings. (See Figure 2-1 below.) Figure 2-1 Flow Direction Through the Quantim, as Indicated by the Arrow Engraved on the Meter/Controller Body. Horizontal Mounting If installing Quantim in a horizontal orientation, liquids should flow in the direction of the flow arrow. ® Situations of entrapped gas in the liquid process should be avoided. In liquid flow applications, it is... -
Page 18: Vertical Mounting
Brooks Instrument Section 2 Installation Figure 2-3 Horizontal Right Side Up Installation Vertical Mounting If Quantim is installed in a vertical orientation, for use in a liquid application, liquid should flow ® upwards through the instrument to help minimize errors due to entrapped gas (See Figure 2-4). For gas flow vertical orientation, flow up or down is acceptable. Figure 2-4 Vertical Flow Up Installation Installation Manual for Quantim ®... -

Brooks Instrument Section 2 Installation RS485 (S-Protocol) Communication Quantim Model QMC is equipped with RS485 communication capability. Refer to Figure ® 2-1 for IP40 or Figure 2-2 for IP6x, Electrical Interfacing for Quantim, to enable the device to communicate via a personal computer, PLC or DCS for process control. Baud rate selections for Quantim with RS485 are: 1200, 2400, 4800, 9600, 19200 and 38400 baud. The device is factory ® set with a baud rate of 19200 and can be changed using the Brooks Expert Support Tool (BEST). The RS485 is a multidrop connection which allows a maximum of 32 devices to be connected to a personal computer or control system. Personal computers are not equipped with RS485 ports as standard. An RS232/USB to RS485 converter or RS485 interface board is therefore required... -

Page 25: Section 3 Operation
Brooks Instrument Section 3 Operation Operating Procedure CAUTION Any sudden change in system pressure may cause mechanical damage to elastomer materials. Damage can occur when there is a rapid expansion of fluid that has permeated elastomer materials. The user must take the necessary precautions to avoid such conditions. -
Page 26: Zero Procedure
Brooks Instrument Section 3 Operation After Quantim has been fully installed, you must perform the zeroing procedure. This procedure ® ensures that the instrument responds properly to zero flow condition and sets a baseline for flow. To perform the zeroing operation on the meter/controller, use the ZERO button, which is located on top right hand side (outlet side) of the instrument. Zero button must be pressed for at least 3 seconds to initiate zeroing procedure. Care should be taken when exercising the zero button. Ensure alignment of the tool on the zero button. Apply a small force to depress the button. -
Page 27: Calibration Procedure
Brooks Instrument Section 3 Operation CAUTION Flow through the instrument during zeroing procedure will result in an inaccurate zero setting. Make sure fluid flow through the instrument is completely stopped during the zeroing procedure. 4. After confirming that fluid flow through the instrument is completely stopped, actuate the zero function as previously stated. Care should be taken when exercising the zero button. Ensure alignment of the tool on the zero button. Apply a small force to depress the button. -
Page 28: General
Brooks Instrument Section 4 Maintenance & Troubleshooting General There are no routine maintenance procedures required to keep your Quantim instrument in good ® operating condition. It is however, very important to keep the fluid entering Quantim clean, and as a ® result periodic replacement of the inlet guard filter is recommended at a frequency determined by the cleanliness of the fluid. At a minimum this guard filter should be replaced annually. WARNING Products in this manual may contain metal or elastomeric seals, gaskets, O-rings or valve seats. It is the "user's" responsibility to select materials that are corrosion resistant and compatible with their process and process conditions. -

Brooks Instrument Section 4 Maintenance & Troubleshooting 5. Verify that the electrical output signal reaches 100% of flow. For MFC applications vary the setpoint over the 1% to 100% range and verify that the output signal matches the setpoint. If possible, connect a flow measurement device (such as a rotometer) to the Quantim outlet to monitor the actual flow behavior. 6. If the Quantim is functioning correctly, the problem may lie elsewhere in the flow system. Re- verify the installation as well as the upstream/downstream fluid system configuration. 7.
