Flow Direction Arrow Medium Mass Flow Meter MOUNTING M-Series Gas Flow Meters have holes on the bottom for mounting to flat panels. See pages 53-80. M-Series Meters can usually be mounted in any position. No straight runs of pipe are required upstream or downstream of the meter.

PRESSURE Maximum operating line pressure for M-Series units is 145 psig (1 MPa). If the line pressure is higher than 145 psig (1 MPa), use a pressure regulator upstream from the flow meter to reduce the pressure to 145 psig (1 MPa) or less.
POWER AND SIGNAL CONNECTIONS Power can be supplied to your meter through either the power jack (power jack not available on CSA/ATEX approved devices) or the 8 pin Mini-DIN connector. An AC to DC adapter which converts line AC power to DC voltage and current as specified below is required to use the power jack.
If you must interface with existing loop powered systems, always use a signal isolator and a separate power supply. Electrical Connections and Basic Wiring http://www.alicat.com/support/instructional-videos/ A remote tare can be achieved by momentarily grounding pin 4 to tare as shown above.

.Net Framework to run properly which is usually preinstalled on the PC. Once downloaded, simply run SerialTerminal.exe and enter the COM port number and baud rate of your Alicat device as prompted. The COM port number may be determined using the Device Manager on the computer, and the default baud rate of an Alicat device is 19200.
For example, A<CR> is equivalent to a<CR>. Polling Mode All Alicat devices are sent in Polling Mode with Unit ID A unless otherwise requested. Polling a device will return a data frame of the current measurements in the device in units shown on the display. See Data Format, later in this section, for more information.
For example, Helium has a gas number of 7. To change the selected gas on unit “A” to Helium, type AG7<CR>.

Operating Principle All M-Series Gas Flow Meters (and MC Series Gas Flow Controllers) are based on the accurate measurement of volumetric flow. The volumetric flow rate is determined by creating a pressure drop across a unique internal restriction, known as a Laminar Flow Element (LFE), and measuring differential pressure across it.
Supported Units: This device supports many different units. You may select the desired units (see page 23). Note that only units appropriate to this device are available for selection. Pressure Units Absolute Gauge Differential Notes pascal hPaA hPaG hPaD hectopascal kPaA kPaG kPaD...

Also, inspect the inside of the upstream connection for debris such a Teflon tape shreds. Note: M-Series meters feature a programmable geometric running average (GRA) that can aid in allowing a rapidly fluctuating flow to be read (see “Pressure Averaging” and “Flow Averaging”...
The Serial Number, Model Number, and Date of Manufacture are also available on the Model Info display (page 18). Cleaning: M-Series Flow Meters require no periodic cleaning. If necessary, the outside of the meter can be cleaned with a soft dry cloth. Avoid excess moisture or solvents.
Option: Totalizing Mode - Meters Meters can be purchased with the Totalizing Mode option. This option adds an additional mode screen that displays the total flow (normally in the units of the main flow screen) that has passed through the device since the last time the totalizer was cleared.
Alicat Portable Meters and Gauges Alicat Rechargeable Flow Meters and Pressure Gauges use a Li-Ion 3.7V cell located in the top section of the device. The Li-Ion cell must not be removed. Normal battery life of a fully-charged cell is 18 hours with a monochrome display or 5 hours with a TFT color display, when the backlight is set to 10.
Pressure Menu for Portable Meters Alicat portable meters are programmed with additional pressure read options. Pressing the pressure button once (upper left) will move the pressure reading to the main display. Pressing the button a second time will open a menu of pressure read options.
Option: Remote Panel Display Our Remote Display option offers the flexibility of using Alicat’s display with units that are embedded inside processes or instrument enclosures. The Remote Display retains all of the same features as our standard display.
Accessory: BB9 Multi-Drop Box The BB9 Multi-Drop Box makes it convenient to wire multiple flow and/or pressure devices to a single RS-232 or RS-485 port. Now with an RS-232 to USB interface! The Multi-Drop Box has nine 8 pin Mini-DIN ports available. The ports are to be used with a standard double ended 8 pin Mini-DIN (DC-62) style cable going from the box to each flow or pressure device.

Technical Data for Alicat MS-Series Mass Flow Meters 0 – 0.5 sccm Full Scale through 0 – 4000 slpm Full Scale Alicat MS instruments are built for use with aggressive gases. For the most part, these instruments maintain the specifications of equivalently ranged M-Series devices.
0 to 0.5 sccm Full Scale through 0 to 3000 slpm Full Scale Alicat MQ units are for high pressure applications. The flow rate is dependent on the pressure in that lower pressures will yield lower flow rates. The Q series should only be ordered after consulting Alicat. MQ units are calibrated for operation at high pressure.
