Gas Mass Flowmeter CMS

Product catalog summary

Overview: This technical guide provides comprehensive information on selecting and configuring Gas Mass Flowmeters, specifically models made from SUS303 and SUS316 materials. It covers specifications, optional parts, and configuration options for various gas types and flow rate ranges.

Specifications: The flowmeters are available in models with flow rate ranges from 0 to 500 mL/min up to 0 to 2000 L/min. They are designed for gases such as air, nitrogen, oxygen, argon, and carbon dioxide, offering high accuracy (±3% RD) and repeatability (0.5% FS) with a rangeability of 100:1.

Materials and Connections: Constructed from SUS303 and SUS316 stainless steel, the flowmeters offer connection options including UNF, Rc, Swagelok, and VCR fittings.

Output and Communication: The devices support analog outputs (4-20mA, 0-5Vdc, 1-5Vdc) and RS-485 communications, featuring event outputs and functions like instantaneous flow rate indication and cumulative flow measurement.

Optional Features: Optional parts include RS-485 communication harnesses and oil-inhibited gas-contacting parts. Inspection results and traceability certificates are available upon request.

Gas Type Configuration: Flowmeters are factory-set for specific gases but can be reconfigured using control panel keys. Changing the gas type may affect the flow rate range.

Measurement Principle: Utilizing a Micro Flow sensor, the flowmeters detect gas flow by measuring temperature differences across a heater, allowing for high-resolution and high-speed response measurements.

Installation and Operation: Designed for horizontal mounting, the flowmeters operate within a pressure range of -0.07 to +1.0 MPa and a temperature range of -10 to 60°C.

Notes and Recommendations: The document includes notes on standard conditions for flow rate conversion and recommendations for selecting gas-contacting parts based on gas type. It advises on gas compatibility with flowmeter models.

Additional Specifications: The document details specifications for hydrogen/helium gas models made from SUS316, including flow rate range, weight, display options, and electrical connections. It specifies that hydrogen and helium gases must be dry and free from corrosive components.

Gas Composition: City gas 13A, derived from LNG, has specific compositions for methane, ethane, propane, and butane, with calorific values of 46MJ and 45MJ.

Flowmeter Features: Capable of measuring instantaneous and cumulative flow rates, the flowmeter offers selectable output signals and event functions for flow rate limits and data output.

Operating Conditions: The devices operate within a pressure range of -0.07 to +1.0MPa and a temperature range of -10 to +60℃, designed for horizontal mounting with specific connection methods.

Accuracy and Measurement: Measurement accuracy is specified for different flow ranges, with a standard reference of 20℃ and 101.325kPa, providing detailed accuracy percentages for various flow rates.

External Dimensions: The document provides dimensions and connection types for different models, with detailed measurements and material specifications, including diagrams for installation and connection types.
