4～20mA.DC (1～5V.DC) signal system is the International Electrotechnical Commission (IEC): analog signal standard for process control system. Our country from DDZ-Ⅲ type electric instrumentation began to use this international standard signaling system, instrument transmission signal using 4 ~ 20mA.DC, contact signal using 1 ~ 5V.DC, that is, the use of current transmission, voltage receiving signal system.

Ash level measurement instruments has always been a difficult problem in power plants because most of the ash delivery systems use time control, and the time setting is relatively conservative and safe due to the unstable amount of feed to the ash tanks, which results in the silo pumps delivering very little ash but using a large amount of compressed air.

Metal tube float flowmeter​ is a commonly used flow measurement instrument, suitable for liquid media flow measurement. The following introduces the principle and characteristics of metal tube float flowmeter:

Accurate measurement of liquid level is crucial for many industries in the industrial production process. Dissolving tanks, as a commonly used equipment, play an important role in chemical, pharmaceutical and food industries. In order to ensure that the liquid level in the dissolving tank can be accurately monitored and controlled, non contact level transmitter have become a viable option!

Level switch types are diverse, such as float level switch, tuning fork level switch, etc., that we need to understand their respective advantages and disadvantages before choosing.

The data acquisition link of the water automation system refers to the process of utilizing various sensors and equipment to automatically collect and transmit hydrometeorological elements such as water level, flow, rainfall, temperature, etc. in the watershed or the measurement area to provide input information for the water automation system.

In the past, we often use the instrument from the user's point of view, to discuss how to improve the measurement accuracy of the instrument, for example, from the installation and maintenance of the commissioning of these aspects. Today we will be from the manufacturers of instrumentation from the point of view, to analyze how to improve the accuracy of the instrument, in this paper we will focus on a data acquisition method, this method is important to improve the measurement accuracy and response speed of the instrument.
