Intelligent online tuning fork density meter

1、 Product principle:

Intelligent online tuning fork density meterBy using a sound frequency signal source to excite a metal tuning fork and causing it to vibrate freely at the center frequency, this frequency is related to the density of the liquid in contact. Therefore, by analyzing the frequency, the density of the liquid can be measured, and then temperature compensation can be performed to eliminate the system's temperature drift; And the concentration is calculated based on the relationship between the corresponding liquid density and concentration.

IIIntelligent online tuning fork density meterFeatures:

1. Adopting a 4-wire system for transmitting 4-20mA output

2. Real time display of five digit density values (four decimal places); Real time indication of current value and temperature

3. Can directly enter the instrument menu on-site to set parameters and debug, easy to operate

4. Equipped with pure water calibration, measurement value fine-tuning, and temperature compensation functions

5. Online real-time measurement, can be directly used for production process control

6. The parts that come into contact with liquids are made of 316 stainless steel, zirconium material, etc., which are safe, hygienic, and have good corrosion resistance.

8、 Installation of resonant densitometer
Due to the requirements of the production process, it is often installed on sites with harsh working conditions. In order to minimize the adverse working conditions of instruments, they should be installed in areas with minimal impact and vibration. When working in flowing pipelines, they should be installed in locations with low flow rates. For this reason, our company has made improvements to the probe. Only by ensuring that the liquid fully contacts the sensor and fully considering the on-site conditions can it achieve its expected accuracy indicators.
Pay attention to the following items during installation:
In terms of instrumentation:
The product must be suitable for easy installation in a convenient location, taking into account full contact between the liquid and the sensor. If the liquid in the pipeline is not fully filled, it should be installed below or on the side of the pipeline, otherwise it will affect the measurement accuracy.
