Burkert 20141169 (Type 8746) is a mass flow controller designed for CO2 carbon dioxide. It operates with a 12 kg/h measuring range and a 1:20 control range. The device requires a 24 V DC supply voltage and utilizes a 4-20 mA signal. It features a G 1/4" internal thread port connection and is calibrated using real gas calibration. The required mounting position is vertical with flow directed downwards.

Safety and Operating Guidelines

Electrostatically Sensitive Components

The device contains electronic components that are susceptible to the effects of electrostatic discharging (ESD). Components that come into contact with electrostatically charged persons or objects are at risk. Meet the requirements specified by EN 61340-5-1 to minimize or avoid the possibility of damage caused by a sudden electrostatic discharge. Do not touch electronic components when the supply voltage is connected.

Electrical Hazard

Touching live parts can result in severe electric shock. Before working on the device or system, switch off the power supply and secure it against reactivation.

Pressure and Temperature Hazards

Medium under pressure can seriously injure people. In the event of overpressure or pressure surges, the device or lines can burst. Before working on the device or system, switch off the pressure and vent or empty the lines. The surface of the device can become hot with fast-switching actuators or with hot media; wear suitable protective gloves.

General Maintenance and Operation

Only work on the device when it is not in use and ensure that the system cannot be switched on unintentionally. Only start the process in a controlled manner following disruptions by first applying the supply voltage or pneumatic supply, then charging the device with medium.
