In the production process of lead-acid batteries, different concentrations of sulfuric acid are required. The concentration of sulfuric acid depends not only on the production steps, but also on the type and size of the battery. The first production step of sulfuric acid is polarization.

At present, the requirements for measuring sugar content, alcohol content, and concentration in fermented wine are: r n1. Therefore, it is necessary to constantly detect the concentration of the original juice at each stage of the process. $r$n2、 The two important parameters of fermented wine are alcohol content and sugar content. At present, most of these two parameters are measured through traditional manual sampling. The method of converting it into sugar content, alcohol content, and concentration is time-consuming and not ideal.

ZHYQ has recently launched a metering device for oil and gas well wellheads to assist in oil extraction. The successful development of this device provides an accurate measurement solution for multiphase flow under multiphase mixed flow process conditions for oilfield production. It provides effective support and means for achieving refined management of single wells, teams (units, blocks, reservoirs) in oilfield production, and will be conducive to driving the improvement of oilfield production technology and management level in the oil extraction industry.

ZHYQ has recently launched the GND15 concentration meter for continuous testing of emulsion concentrations in industries such as petroleum, chemical, and mining. This product is mainly used for the preparation and detection of weight percentage concentrations of cooling and cooling emulsions in the mechanical processing industry, as well as M-IO and MDT emulsions commonly used in mines. It provides a convenient method for safely and economically preparing emulsions.

The main function of a differential pressure transmitter is to directly sense the pressure element (located inside the lower housing). Most industrial DP transmitters are equipped with diaphragms as pressure sensing elements. This diaphragm is a mechanical device. It is located between two pressure inlets. The diaphragm will deflect due to the applied pressure. The deflection is converted into an electrical signal. This is usually done by sensors. The commonly used sensors are (a) strain gauges, (b) differential capacitors, and (c) vibrating wires. The sensor output is proportional to the applied pressure.

The Internet of Things consists of several technological layers that enable ordinary things to share data and ultimately provide intelligence, autonomous action, and value, which largely depend on the quality of the data itself. Therefore, sensors are an indispensable part of the IoT technology stack and a key factor in the success or failure of every IoT system development.

Tilt angle sensors use the principle of inertia, based on Newton's second law. According to basic physical principles, within a system, velocity cannot be measured, but acceleration can be measured. If the initial velocity is known, the linear velocity can be calculated by integration, and then the linear displacement can be calculated.

The emulsion concentration meter has different measurement ranges of 0-10%, 0-20%, 0-32%, 0-50%, 28-62%, 58-92%, 0-80%, 0-90%, etc. It is used to detect the weight percentage concentration of water-soluble cutting fluid (cutting oil), providing great convenience for accurately preparing cutting fluid (cutting oil). It can be applied to manage the degree of contamination of cleaning fluid used for cleaning metal machining parts, and can be used for factory preparation of cutting fluid, cutting fluid, and quenching fluid. Can be applied in fields such as mechanical processing, mining selection, and underground support.

Application Overview: $r $n emulsion has a wide range of applications in coal mining production activities, especially as a working medium for hydraulic systems such as coal mining machines, hydraulic supports, and hydraulic pillars in fully mechanized coal mining faces. It not only plays a role in transmitting power, lubrication, and cooling, but also has an inhibitory effect on corrosion and rusting. Emulsion has become the "blood" of hydraulic systems. At present, coal mines in China widely use water in oil emulsion with a mass concentration of 3% -5%, which is prepared by adding 3% -5% emulsion oil by weight and 97% -95% water to form an emulsion.
