Liquid Flow Meter Supporting 80 Types of Chemicals Launched, Reducing Flow Errors Due to Liquid Temperature Changes

Multi-Flow R™ (MFR) With/Without Display

Challenges in Flow Management for Semiconductor and Chemical Processes

In semiconductor manufacturing equipment and chemical supply facilities, challenges include selecting appropriate materials for the wetted parts based on the fluid used and flow errors caused by changes in liquid temperature.

Multi-Flow R achieves compatibility with various chemicals and stable flow measurement through its New PFA wetted structure and temperature compensation function.

Benefits of Introducing Multi-Flow R™

It compensates for flow fluctuations due to temperature changes, contributing to stable flow management and quality maintenance in wet processes.

Temperature Compensation Function

Typical Vortex Flow Meter (without temperature compensation)

When the fluid temperature changes, the vortex frequency fluctuates due to factors like viscosity changes. This affects the detection signal, potentially leading to errors in flow measurement accuracy.

This necessitates monitoring and manual valve adjustments, increasing labor costs.

Multi-Flow R™

Equipped with a temperature sensor in the flow path, it automatically compensates for flow rate even when the water temperature changes, eliminating the need for monitoring and adjustment.

Product Features

Reduces accuracy errors due to liquid temperature changes by measuring fluid temperature with a built-in temperature sensor and applying temperature compensation.

Uses only New PFA for wetted parts, compatible with approximately 80 types of chemicals.

Compact design, with no moving parts or O-rings.
