Particle measurement technology is complex, and choosing the right particle counter requires careful consideration. Different liquids and purposes place different demands on the measuring devices. If you want to find the ideal particle counter for you, you should familiarise yourself in advance with the key criteria and the specific requirements of your application.
Key Criteria for Selecting a Particle Counter
To ensure that the measuring device is optimally suited to your needs, consider the following aspects:
Each liquid has its own physical and chemical properties that influence the choice of sensor and materials used. Different particle counters are designed for different types of liquid, such as water- or oil-based fluids.
- Properties of the Liquid
The nature of the liquid – in particular its viscosity – determines the required pressure to pass it through the sensor measuring cell. Viscous substances need a stronger pump or lower flow rate than less viscous liquids, making certain sensors more or less suitable. The temperature of the liquid is a relevant factor, as it can also affect the viscosity.
- Particle Concentration
Particle concentration indicates how many particles are present in the liquid per millilitre. The choice of sensor and measurement technique depends on whether the liquid usually has a low or high particle count.
- Particle Size
Knowing the size of the largest particles within the fluid is essential for the correct selection of sensor. For larger particles, the sensor needs a correspondingly larger measurement cell to ensure that the particles can pass through without blocking the flow path.
- Environmental Conditions
Depending on the application-specific requirements for particle measurement, there are three different types of particle counters:
- Online particle countersthat are permanently installed in systems and are used for continuous condition monitoring.
- Laboratory instrumentsdesigned for simplistic user-friendly measurements from sample bottles in the lab.
- Portable particle countersthat offer high flexibility as they can be used both on-site and for online or offline measurements (bottle samples). Depending on the application, the working system pressure is also important when selecting the correct instrument.
Scheduled calibration of the particle counter confirms instrument accuracy and ensures standard-compliant measurements. It is important to know whether and according to which standard the manufacturer of the particle counter performs calibrations and whether there is an after sales support serviceable available for the device. The service warranty, calibration interval, and provision of a replacement device during the service period should also be clarified in advance.
