Getting Started Getting to Know Your CODA KM-Series Coriolis Mass Flow Meter Connectors and Buttons The drawing on the following page represents a typical KM-Series mass flow meter. Your device’s appearance and connections may differ. Mounting All CODA KM-Series mass flow meters have mounting holes on the bottom for convenient attachment to flat panels. - Page 5 LED Power Indicator Male DB-15 Connector USB Type C Tare Button ⁄ VCR® Outlet ⁄ VCR® Inlet Mounting Holes: 2× M5×0.8 10mm 0.207 1.024 0.914 1.731 CODA-Series Coriolis mass flow meter operating manual...

Page 6: Plumbing
Plumbing Process Ports Your CODA KM-Series Coriolis mass flow meter has been shipped with ¼″ VCR®-compatible male process connections. Use in-line filters to prevent large particulates from entering the device. The suggested maximum particulate size is 20 microns for meters. Warning: Do not use pipe dopes or sealants on the process connections, as these compounds can cause permanent damage to the meter should they get into the flow stream. -
Page 7: Power And Signal Connections
Power and Signal Connections The USB-C connector on top of the device provides a serial interface to CODA KM-Series mass flow meters. Meters can be powered via the USB-C, DB-15, or M12 connector. The USB-C connector is not available on IP67- rated devices. -
Page 8: Taring Your Device
Taring your Device Taring ensures accurate measurements by giving the device a zero reference. The taring process takes 10 seconds to complete once it begins. Prior to taring, flow fluid through the device and then stop flow to establish a no-flow condition while there is fluid present throughout the instrument. For best results, allow the electronics and the flow 15 minutes to reach a steady state temperature before taring. -
Page 9: Communication
Communication Analog Communication KM-Series mass flow meters with a DB-15 connector include an analog output for both mass flow and density. CODA instruments with the optional 8-pin M12 connector have a single analog output for mass flow (page 7). Both of these outputs are linear across the entire range, provided the load impedance is within the nominal values specified in the table below. -
Page 10: Analog I/O Data Ranges
Analog I/O Data Ranges Analog inputs and outputs for your device were calibrated at the factory. By default, the full scale flow range maps 1:1 to the full scale voltage or current range of your device with a small overrange allowed. Custom analog ranges may also be set from the factory. -
Page 11: Multidrop Information
Multidrop Information CODA devices equipped with an RS-485 interface can operate on networks with other devices. The CODA RS-485 transceiver is a 1/2 unit- load transceiver. When deploying CODA devices in an RS-485 network with multiple types of devices be sure to confirm that the total load of all devices does not exceed 32 unit loads on an unrepeated network segment. -
Page 12: Modbus Reading And Status Registers
Reading Process Data Alicat CODA KM-Series mass flow meters make no distinction between “Input” and “Holding” registers. Modbus function codes FC03 and FC04 can be used interchangeably to read data from the device. Sensor and process values are stored as big-endian, 32-bit IEEE-754 floating point numbers spanning two registers. -
Page 13: Status Flags
Status Flags Interpretation Tare in progress Density under-range Density over-range 3–31 Reserved Special Commands You can access special control functions on CODA KM-Series mass flow meters with an FC16 write to registers 1000..1001. Special commands consist of a Command ID and a Command Argument written in a single pass to these registers. -

Page 15: Alicat's Coda View Interface
Alicat’s CODA View Interface Alicat’s CODA View is a pre-configured LabVIEW program for digital communications with CODA-Series devices only (other Alicat models will not communicate through this program). It is available as a stand-alone executable that only requires the free LabVIEW 2018 and NI-VISA 2018 runtime engines built by National instruments. -
Page 16: Maintenance
Maintenance Cleaning This device requires minimal maintenance. If necessary, the outside of the device may be cleaned with a soft dry cloth. Avoid excess moisture or solvents. CODA KM-Series mass flow meters used with gas require no periodic cleaning, provided they have been flowing clean, dry gas. CODA KM-Series mass flow meters used with liquids require some precautions to avoid contamination and/or corrosion damage. -
