Acoustic impedance concentration meter

Acoustic impedance concentration meter is an instrument that uses the principle of ultrasonic acoustic impedance to measure the concentration or density of solid-liquid two-phase slurry. It calculates the density or concentration of the slurry by analyzing the reflection and transmission characteristics of ultrasound in the slurry.

Working Principle:

The working principle of acoustic impedance concentration meter is based on the concept of acoustic impedance. Acoustic impedance is the product of sound velocity and medium density, reflecting the propagation characteristics of sound waves in different media. When the ultrasonic signal emitted by the ultrasonic probe comes into contact with the slurry, a part of the energy will enter the slurry, and another part will reflect on the surface of the slurry and the probe. The energy reflected and transmitted is related to the acoustic impedance of the slurry. By analyzing and processing these acoustic energy, the density or concentration of the slurry can be calculated.

　　Acoustic impedance concentration meterThe host pre stores temperature and sound velocity characteristic parameter curves for various media, and calculates the required process control parameters based on these curves.

The host is based on dual microprocessor digital signal processing technology, which can work stably and reliably even under harsh working conditions, making it very suitable for controlling complex process. The input and output configuration is flexible, and temperature measurement can be completed through the built-in temperature probe. It can simultaneously measure and display concentration and flow rate. There are two types of measuring probes for acoustic impedance concentration meters, one is plug-in and the other is clip on. When using a clamp probe, calibration is usually required. The plug-in probe is particularly suitable for concentration measurement in batch reactors and mixers, with precision and reliability. After factory calibration, there is no need to zero or set on site, and measurement can start immediately after installation.

The acoustic impedance concentration meter emits a signal from the probe head:

1. Part of the energy enters the slurry

2. Part of it is reflected on the surface of the slurry and probe.

3. The amount of reflected energy is related to the acoustic impedance of the slurry.

Temperature correction: The temperature measurement is 0.1 degrees, using a high-precision PT1000 platinum resistor. The probe can be temperature calibrated in the laboratory, and temperature errors can be compensated for through software.
