Particle contamination analysis plays an important role in laboratories, pharmaceutical facilities, cleanrooms, and industrial manufacturing environments. A particle counter is a precision laboratory instrument designed to detect, measure, and classify particles present in air, liquids, and process samples.

Modern particle counter equipment with 8 simultaneous size channels provides detailed particle distribution analysis by measuring multiple particle sizes within a single sampling cycle. This advanced capability allows laboratories to identify contamination patterns, monitor cleanliness levels, and maintain consistent quality standards.

Whether used as an airborne particle counter for cleanroom monitoring, a liquid particle counter for pharmaceutical testing, or a complete particle counting system for industrial applications, this instrument provides accurate particle measurement and reliable contamination assessment.

What Is a Particle Counter?

A particle counter is an analytical laboratory instrument used to determine the number and size distribution of particles present in a sample. It detects microscopic contaminants in gases, liquids, and other materials by using advanced sensing technologies.

Depending on the application, particle counters are used for:

Air cleanliness monitoring

Liquid contamination testing

Pharmaceutical quality control

Water purity analysis

Industrial process monitoring

Most modern particle counter machines use laser-based optical detection technology. When particles pass through a detection area, the instrument measures the scattered light signal and converts it into particle size and concentration data.

Importance of 8 Simultaneous Size Channels

The ability to analyze 8 simultaneous size channels is a major advantage in particle measurement technology. Traditional instruments may analyze limited particle ranges, while multi-channel particle counters provide a broader understanding of contamination levels.

Introduction

A  Coriolis mass flowmeter is widely used for direct mass flow measurement in laboratory research, pharmaceutical manufacturing, chemical processing, biotechnology, food production, and precision industrial operations. Unlike conventional flowmeters that estimate flow based on volume, a Coriolis mass flowmeter directly measures the actual mass of liquids and gases flowing through vibrating tubes. This provides high measurement accuracy for low-flow dosing, batching, dispensing, and process control. The Coriolis Mass Flowmeter 20CMF-100 simultaneously measures mass flow, density, and temperature, enabling efficient monitoring while reducing material waste and improving production consistency.

What Is a Coriolis Mass Flowmeter?

A Coriolis mass flowmeter directly measures the mass flow of liquids, gases, and slurries without requiring compensation for pressure, temperature, or viscosity changes. The instrument contains one or more vibrating tubes through which the process fluid flows. As the fluid moves through the tubes, the Coriolis effect creates a measurable phase shift proportional to the mass flow rate. Sensors detect this shift and convert it into accurate flow measurements while also determining density and temperature. These capabilities make the coriolis flowmeter an important instrument for analytical laboratories and industrial process control.

Coriolis Mass Flowmeter Working Principle

The Coriolis mass flowmeter working principle is based on vibrating flow tubes. When no fluid passes through the tubes, vibration remains symmetrical. During flow, the Coriolis force causes a slight twist between the inlet and outlet sections, creating a phase difference. Electronic sensors measure this difference to calculate mass flow directly. The vibration frequency is also used to determine fluid density, while integrated sensors monitor temperature. Since the measurement is based on mass rather than volume, changes in fluid properties have minimal impact on accuracy.

Why It Enables Precision Low-Flow Dosing

Low-flow dosing requires highly accurate measurement of small fluid quantities. A Coriolis mass flowmeter provides:

Direct mass flow measurement

High repeatability for batching and dispensing

Simultaneous density and temperature monitoring
