YZ6406 Fixed value controllerDetailed product description：

The YZ6406 constant value controller is a computer flow meter that uses STC89C58RD+advanced microcontroller as the CPU for quantitative control. The YZ6406 constant value controller is a set of reliable, powerful, stable, adaptable, and easy to maintain constant value controllers developed by our company based on a large amount of practical experience and production requirements of users, combined with continuous improvement during user use.

The YZ6406 constant value controller has a simple structure, stable performance, complete functions, and flexible configuration. When matched with a flow meter, it can measure mass or volume and complete quantitative control. It can achieve automatic filling by controlling the pump or solenoid valve. The YZ6406 constant value controller can conveniently input parameters through the keyboard and display parameter values such as instantaneous quantity, cumulative quantity, time, and date. The YZ6406 constant value controller adopts a disc mounted structure, which is reliable in structure, easy to operate, and aesthetically pleasing in appearance. The YZ6406 constant value controller is equipped with a temperature sensing interface, which can be connected to the upper management system for automatic control. The instrument also has functions such as temperature and density compensation, communication, printing, and power failure protection. The direct AC 220V input from the mains makes the installation of the YZ6406 constant value controller very convenient. Suitable for single channel liquid quality measurement, it can complete separate barrel and loading, and can be widely used in industries such as edible oil filling measurement, chemical raw material liquid measurement, pharmaceutical measurement, brewing measurement, beverage measurement, lubricant measurement, alcohol measurement, etc. in non explosion proof environments. It can be applied in harsh environments. This product has high measurement accuracy, strong anti-interference ability, and data protection, which are at the leading level among similar products in China. It is an ideal instrument for achieving quantitative filling.

Introduction to the working principle and main functions of the instrument

Overview
The volumetric flowmeter is used for the first measurement of liquid quantitative filling. The flowmeter is equipped with our company's GDF-II type jitter detection device, which can identify the positive direction of transmission. In the process of liquid transportation, the transmitter transmits pulse signals to the constant value controller, and each pulse signal represents the volume of liquid passing through (unit: cubic meter). Temperature measuring platinum resistors are installed on the liquid transportation pipeline to monitor temperature changes during the liquid transportation process in a timely manner and transmit data to the constant value control instrument.
