Level measuring instruments applied in beverage pharmaceutical industry

With the advent of the era of intelligent manufacturing, how can pharmaceutical companies that take quality as their lifeline carry the express train of "intelligent manufacturing"?

A major issue faced by many pharmaceutical companies. In the intelligent production process, liquid level detection and monitoring are used in the production of medicine, beverage and other industries.Level measuring instruments price -Hiltech

Playing an important role, liquid level monitoring directly affects the quality of products and even whether the production process can go smoothly. At the same time, as an important measuring instrument, liquid level detection equipment is one of the important guarantee elements for the safety and control of the production process. Qualified liquid level testing equipment and excellent liquid level detection technology not only escort the quality of raw materials, semi-finished products and finished products for pharmaceutical enterprises, but also GMP plays an important role in the implementation process. Therefore, in order to ensure the consistency of product quality, only scientifically select the liquid level detection technology can ensure the reliability and stability of the detection results.

How to choose level instrumentation?

Generally speaking, the factors that beverage companies and pharmaceutical factories should consider when selecting liquid level measuring instruments mainly include the following:

1. Measurement object

The physical and chemical properties of the liquid to be tested, such as acidity, alkalinity, conductivity, whether foaming, and the pressure and temperature range of the application environment, etc.

2. Measurement and control requirements

Whether it is on-off measurement or continuous measurement, whether it is contact or non-contact measurement, as well as measurement range and accuracy, safety and reliability, and construction convenience.

3. Cost-effective

At present, there is no single liquid level measurement technology that can adapt to all media or environments. This is because the working conditions vary widely, and different working conditions require different types of instruments to adapt to them. Since the production process of beverages and medicines requires real-time monitoring, automatic control, and scheduling management to achieve the purpose of reducing costs and increasing efficiency and ensuring safety, it requires enterprises to focus on the characteristics and advantages of each measurement method according to the measurement requirements and use environment. , Scientific selection, on the premise of ensuring product quality, purchase cost-effective products with moderate prices to ensure the reliability and stability of testing. Instead of blindly pursuing low prices and purchasing instruments with substandard quality, the gains outweigh the losses in the end.

Among the many instruments, the magnetic level gauge and the ultrasonic level gauge are the two most commonly used liquid level measuring instruments. Among them, the magnetic flap level gauge can achieve a high degree of sealing and anti-leakage, and is suitable for high temperature, high pressure, and corrosion-resistant occasions, but the working pressure on site should not be too large. It makes up for the defects of the glass plate (tube) level gauge with poor indication clarity and easy breakage, and has no blind spot in the whole process measurement, with clear display and wide measurement range. In addition, depending on the density of the liquid, the magnetic float needs to be calibrated with the actual medium.

The ultrasonic level gauge utilizes the characteristics of wave propagation in the medium, and has the characteristics of easy installation and high flexibility. It is mainly used in storage tanks and open pools. Usually can be installed at height for non-contact measurement. However, it is susceptible to energy loss from ultrasonic propagation.

Specifically, when the ultrasonic wave encounters the phase interface during propagation, part of it is reflected back, and the other part is refracted into the adjacent medium. When it is transmitted from gas to liquid or solid, or from solid or liquid to air, almost all reflection occurs due to the large difference in medium density, and when the ultrasonic level gauge is used in environments containing steam and dust, the detection distance will be significantly shortened, so it is not recommended to use the ultrasonic level gauge in an absorbing wave (such as foam, etc.) environment.Level measuring instruments supplier -Hiltech

A good liquid level detection technology should not only ensure stable, safe and reliable measurement under the premise of meeting process requirements, but also it should be easy to install, simple to maintain, and economical. The factors that pharmaceutical companies should consider when choosing liquid level detection technology and liquid level timing include:

(1) The measurement object, the physical and chemical properties of the liquid to be measured, such as acidity, alkalinity, conductivity, whether foam is generated, and the application ring ambient pressure and temperature range, etc.

(2) Measurement and control requirements, whether it is liquid level measurement or continuous measurement, contact or non-contact measurement, and measurement quantity range and accuracy, safety and reliability and construction convenience.

(3) Low cost.
