Introduction Welcome With red-y you get the latest, most modern CMOS sensor technology. CMOSens is a technology label and stands for a modern process in which the sensor and the signal processing are combined on a highly integrated chip. This manual will familiarize you with the installation and operation of your red-y . We therefore ask you to read this manual carefully and to contact your sales partner with any questions or doubts.

Introduction Tips and Warnings Before putting the instrument into use, these operating instructions should be read thoroughly. Improper use, errors for lack of understanding and the consequences arising from this, can lead to the destruction of the instrument or even the endangerment of personnel. The equipment should be put into operation and serviced by appropriately qualified personnel only.
Mode of Operation A bit of theory Measuring principle The measuring principle of thermal flow measurement is perfectly suited for the measurement of gas flows. One of the significant advantages is that the measurement is largely independent of pressure and temperature. By contrast to volumetric principles, pressure and temperature do not have to be additionally measured.

Mode of Operation The digital intelligence linked with the CMOSens sensor permits the emission of a fully calibrated, temperature-compensated output signal. The CMOSens ‘intelligence’ integrated onto the chip thus facilitates an extremely simple processing of the emitted measurement data. CMOS is a standard technology for the manufacture of integrated circuits.

Technical Information Measurement Ranges Red-y measurement and control devices are supplied with standard measurement ranges for air. As an option, the devices are available with individual measurement ranges and, upon request, can be calibrated with other gases. Standard Measurement Ranges Code Meas.
Technical Information Temperature Compensation Thermal mass flow meters measure the flow of gases to a large extent independent on pressure and temperature. Varying temperatures are automatically compensated by the measurement device. The sensor measures gas temperature and automatically calculates a correction value using a three-dimensional value table.
Mounting & Installation Mounting & Installation General Tips Check the packet for external damage and contact us immediately in the case of visible damage. Compare the contents of the packet with the delivery slip and check for completeness and technical compliance.
Mounting & Installation Electrical Connection / Power Supply With the battery-operated devices, mount the battery module. Then the measuring device is ready for use. The useful life of the battery module is about 2 years, but this depends on use. With constantly changing flow rates, the useful life may be shorter.
Operation & Service Operation & Service Heat-Up Time Right when the device is turned on, red-y is ready for use. For the most precise measurements, however, red-y is ready in 30 minutes (option of external feed). Before turning on, please be sure that the wiring is correct and is installed according to the installation plan, and that the gas connections are also mounted in accordance with the installation instructions of the manufacturer.
Operation & Service Battery Replacement If ‘low bat’ appears in the display, we recommend that you change the battery or at least have a new battery module available (Art. Nr. 328-2211). This module can be obtained from your Insentys sales partner. We recommend the following procedure with the replacement of the battery: Changing the battery requires no tools at all.

Totalizer Totalizer General The Totalizer function can be activated by the manufacturer . Function The instrument calculates the integrated value of the gas volume. The added up value is periodically displayed and stored in intervals of 15 minutes in the non-volatile storage (EPROM). In the event of a power disruption, the Totalizer therefore displays the correct total volume.
