10 M Series Mass Flow Meter Operation The M Series Mass Flow Meter provides a multitude of useful flow data in one simple, rugged device. The M Series can have several display “modes” depending on how the device is ordered. All M Series meters have a default Main Mode, Select Menu Mode, a Gas Select...

11 Gas Absolute Pressure: The M Series flow meters utilize an absolute pressure sensor to measure the line pressure of the gas flow being monitored. This sensor references hard vacuum and accurately reads line pressure both above and below local atmospheric pressure. This parameter is located in the...

12 Select Menu Mode Pushing “Mode” once will bring up the “Select Menu” display. Push the button nearest your selection to go to the corresponding display. Push “Mode” again to return to the Main Mode display. ( Note: If your meter was ordered with Totalizing Mode option (page 36), pushing the “Mode...

13 Communication Select Mode The Communication Select mode is accessed by pressing the button below “Comm. RS-232” on the Select Menu display. The screen will appear as shown in Figure 9 below.

14 Manufacturer Data “Manufacturer Data” is accessed by pressing the “Mfg. Data” button on the Select Menu display (Figure 7). The “Mfg 1” display shows the name and telephone number of the manufacturer. The“Mfg 2” display shows important information about your flow meter including the model number,...

15 V Series Volumetric Flow Meter Operation The V Series can have several display “modes” depending on how the device is ordered. All V Series meters have a default Main Mode,a Select Menu Mode, a Gas Select Mode (the Gas Select Mode may not be available on meters calibrated for a custom gas or blen...

16 Flashing Error Message: Our volumetric flow meters and controllers display an error message (VOV = volumetric overrange) when a measured parameter exceeds the range of the sensors in the device. When any item flashes on the display, the flashing parameter is not accurate. Reducing the value of th...

Type “*@=@” followed by “Enter” (or using the RS-232 communcation select menu, select @ as identifier and exit the screen). If data still does not appear, check all the connections and com port assignments. Chan...

20 Sending a Simple Script File to HyperTerminal® It is sometimes desirable to capture data for an extended period of time. Standard streaming mode information is useful for short term events, however, when capturing data for an extended period of time, the amount of data and thus the file size can ...

21 Operating Principle All M or V Series Gas Flow Meters 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 acros...

24 This reduces to: Pa V a / Z a Ta = P s V s / Z s Ts , eliminating R and n. Our mass flow meters model gas flows based upon the non-ideal gas characteristics of the calibrated gas. The flow corrections are normally made to 25 C and 14.696 PSIA and the compressibility factor of the gas under those ...

27 Volumetric Flow Meters Under Pressure V Series Volumetric Flow Meters are intended for use in low pressure applications. This is because an accurate measurement of the volumetric flow rate by means of differential pressure requires the flow at the differential pressure sensor to be in a laminar s...

28 TROUBLESHOOTING Display does not come on or is weak. Check power and ground connections. Flow reading is approximately fixed either near zero or near full scale regardless of actual line flow. Differential pressure sensor may be damaged. Avoid installations that can subject sensor to pressure dro...

29 Slower response than specified. M or V Series meters feature an RS-232 programmable Geometric Running Average (GRA). Depending on the full scale range of the meter, it may have the GRA set to enhance the stability/readability of the display, which would result in slower perceived response time. I...
