Description Vendor
  • The red-y industrial series is a high-accuracy thermal mass flow meter and controller for gases, featuring IP67/NEMA 6 protection and ATEX certification for use in hazardous environments. It offers two versions: Standard (±1.0% full scale, 1:50 turndown ratio) and Hi-Performance (±0.3% full scale + ±0.5% reading, 1:100 turndown ratio).
  • The devices support multiple connection options, including cable glands and M12 connectors, and are compatible with industrial communication protocols like Profibus, Profinet RT, and EtherCAT. They also support multigas measurement, with options for up to 10 different gases or gas mixtures.
  • The setup tool get red-y enables remote maintenance, gas type switching, and parameter adjustment. The series is designed for rugged environments and includes a 3-year warranty, with high-quality components ensuring long-term reliability.

Use Cases

  • Accurate measurement of gas flow in industrial environments
  • Remote maintenance and setup of flow meters and controllers
  • Measurement of multiple gases or gas mixtures
  • Integration with industrial networks like Profibus, Profinet, and EtherCAT

Capabilities

  • Thermal mass flow measurement and control for gases including hydrogen, air, and inert gases
  • Operation at pressures from 0.2 to 11 bar(a)
  • Operation at ambient and gas temperatures from 0 to 50 °C
  • Digital (Modbus RTU, RS-485) and analog I/O as standard, with optional industrial Ethernet interfaces
  • Multigas operation configurable via software without hardware changes
Vögtlin Instruments GmbH Vögtlin Instruments GmbH is a manufacturing company specializing in mass-flow meters and controllers calibrated for hydrogen. The broader business is instrumentation-oriented, with sensors and analyzers supplied either as stand-alone instruments or embedded into machines, process skids, safety systems, laboratories, and plant automation so operating conditions can be measured and documented. The company’s products typically provide information to a larger control, safety, quality, or test system, making measurement accuracy, response behavior, interfaces, calibration, and environmental suitability part of the integration task. For hydrogen, the company’s actual role is defined by the specific pressure, flow, gas-detection, concentration, quality, temperature, electrical, or other measurement functions described in its portfolio; different suppliers cover different parts of this measurement layer. Its instruments measure and regulate low to medium gas flows in electrolyzer development, fuel-cell testing, laboratories, and process systems. The company provides compact digital flow devices and application support for precise hydrogen dosing and measurement. Within the hydrogen value chain, Vögtlin Instruments GmbH therefore supplies instrumentation, monitoring, or safety technology to OEMs, test organizations, plant integrators, infrastructure developers, and industrial operators handling hydrogen.
