note that the K-factors as used in the traditional capillairy MFM/MFC cannot be used for CMOS mass flow meters. Please contact the factory for additional information. Note Please note that, among other effects, the zero-point error (offset display) will be higher if the device is not operated with the type of gas, for which it had been calibrated. -
Page 21: Filter Settings
Filter settings 2.22. The filter settings smoothens the reading of pulsating or noisy flows. It can be set through the set- up menu. Higher filter settings will slow down the response time of the unit. Please always first try to find and remove the cause of your noisy or pulsating flow e.g. add volume to your system. -
Page 22: Installation And Commissioning
3. Installation and Commissioning Mounting Position and Mounting Location 3.10. Although the recommend mounting position is horizontal, the unit can used be upright, vertical or upside down. With a vertical mounting position, dependent on the type of gas and at pressures above 5 bara (72 psia, 500 kPa(abs)), a zero-point offset can be possible. -
Page 23: Fittings And Filters
• The size of the pipe must be matched to the measuring/control device. A diameter that is too small results in an increased pressure drop. • Check for any leaks before commissioning the devices. • For maintenance work, we recommend that a bypass system is used. This is particularly important where the gas supply must not be interrupted. -
Page 24: Electrical Power Supply
In pressurized-air applications using compressors, the air must be dry and free of oil. Please ensure that a suitable processing unit is located before the devices. In the case of gases from cylinders, in general no filter is needed. For more information, see chapter Maintenance. -

Please note that if the flow rate exceeds the full scale of the unit (overflow), the totalized value will not be correct. Even if there is an overflow the totalizer operation will continue normally. However, since the flow value is limited the totalizer is totalizing the limited flow value only.

- Page 46 4.12.3 Units In the “Units” menu you can set the required engineering units for the totalizer and the flow indication. If there is a unit selected with too many digits, the device will show: “Out of range” on the display. If you select a totalizer unit that would create too many digits the totalizer will show 9999999.
- Page 47 when the flow shows quick changes. So when the flow is quickly rising or falling it will take less averages in it calculations. On this way the unit will react faster to changes in the flow. Averaging filter The averaging filter is a “moving average filter”. It calculates the average value of a number of measurements and shows the average on the display.
- Page 48 Notes: 1. Because the value is right-aligned, it is possible that depending on the actual flow you can see a change in the number of digits behind the decimal point. For example if the flow is changing from 2 to 2.01 and then 2.1 you can see: 2.0, 2.01 and 2.1 on the display. 2.
- Page 49 4.12.7 Battery Auto Off To extend the battery life to the maximum we recommend that you set this menu so that, when powered with a battery, the RedyCompact will switch off automatically after the indicated number of minutes. Please note that this menu has no effect if the unit is powered by USB or the external 24 VDC .

Page 50: Maintenance
Maintenance When operated properly and with the use of clean and dry gas, RedyCompact devices do not require any routine maintenance. There are no internal moving parts in the measurement part of the device. However, we recommend that the calibration is checked after 12 months. If your RedyCompact is still within tolerance, this time interval can be extended. -
