eyc-tech FDM06-I Venturi Thermal Mass Flow Meter

Product catalog summary

Applications
The document outlines the applications of the Venturi Thermal Mass Flow Meter, FDM06-I, which include compressed air systems, pneumatic systems, dryers, air consumption monitoring, and pipeline leak monitoring.

Features
The FDM06-I features precise measurement using a unique Venturi tube structure, a 2-inch LCD screen for easy configuration, and display features that show both instant and cumulative measurements. The screen can rotate 90 degrees for better viewing. It supports multiple pipe diameters (DN15, DN25, DN40, DN50) for easy installation and offers an accuracy of ±1.5% F.S. with a pipeline withstand pressure of 16 bar. The device provides multiple outputs including analog, relay, and RS-485.

Specifications
The flow meter uses a hot-wire sensor with a turndown ratio of 100:1. It has a measuring range of up to 500 Nm³/h depending on the pipe size. Output signals include 4-20 mA, 0-10 V, relay, and RS-485, with a warm-up time of 60 seconds and a response time of t90≦6 seconds. It operates with non-corrosive gases at temperatures between 0-50°C and humidity levels of 20-90% RH. The device is powered by DC 24 V with a current consumption of 110 mA and a relay capacity of 6 A.

Measurement Principle
The FDM06-I employs a Venturi tube based on the Venturi effect, which measures flow rate by calculating the differential pressure at two points. This method allows for high accuracy and low pressure loss, suitable for various fluids including gases, liquids, and steam. The robust structure requires minimal maintenance.

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

Ordering Guide
The document provides an ordering guide with options for diameter and range, connection type, output, and additional options. It also mentions the availability of test reports from YUDEN-TECH CO., LTD. Calibration Laboratory, accredited by ILAC/TAF.

| Measurement Principle | ■ Venturi tube The Venturi tube is a ﬂow measurement device designed based on the Venturi eﬀect and is often used in conjunction with diﬀerential pressure transmitters. The ﬂow rate is calculated by measuring the diﬀerential pressure at two points in the Venturi tube. When ﬂow passes through the narrow center of the Venturi tube, its velocity increases while the pressure decreases; this phenomenon is known as the Venturi eﬀect. According to Bernoulli's principle and the continuity equation, the pressure diﬀerence between the inlet section and the narrow center is proportional...
