eyc-tech FTM06D-I Inline Type Air Flow Transmitter

Product catalog summary

Applications
The document outlines the applications of the FTM06D-I Inline Type Air Flow Transmitter, which include use in compressed air systems, pneumatic systems, refrigerated and adsorption air dryers, air consumption monitoring, and pipeline leak monitoring.

Features
The device features a thermal mass flow sensor with an accuracy of ±1.5% F.S. and a maximum operating pressure of 16 bar. It offers multiple output options including 4-20 mA, 0-10 V, RS-485, frequency, and pulse. The transmitter supports a full pipe size range (DN15, DN25, DN40, DN50) and is easy to install. It includes built-in temperature compensation for accurate measurement and is calibrated using a sonic nozzles calibration system. The housing is made of stainless steel with an aluminum alloy pipe, and it can connect to software via RS-485 for data logging and graph recording.

Specifications
The transmitter uses a thermal mass flow sensor with varying measuring ranges depending on the pipe size. It supports output signals of 4-20 mA, 0-10 V, RS-485, frequency, and pulse. The device has a warm-up time of about 60 seconds and a response time of t90≤3 seconds. It operates at a temperature range of 0-50°C and a humidity range of 20-90% RH. The power supply is DC 24 V ±10%, with a current consumption of 110 mA. The device is certified with CE and has an IP65 rating, with an option for IP67.

Calibration System
The calibration system is based on ISO 9300 standards for flow measurement using critical flow venturi nozzles. It covers an air volume range of 0.5 m³/h to 1000 m³/h.

Temperature Compensation Verification
The document includes a 3-cycle linear curve graph demonstrating the temperature compensation capabilities of the device.

Dimensions
Detailed dimensions are provided for different pipe sizes (DN15, DN25, DN40, DN50) with specifications for installation using M4 screws.

Ordering Guide
The ordering guide specifies options for diameter and range, connection type, output, display, and additional options.

Air Velocity / Flow Conversion Table
A conversion table is provided for different pipe sizes, showing air velocity and corresponding air flow rates.

Additional Option Test Report
The document mentions a test report from YUDEN-TECH CO., LTD. Calibration Laboratory, accredited by ILAC/TAF, complying with ISO/IEC 17025 standards.
