Flow recorders are widely used in the water treatment industry, and many companies strive to record daily flow for ease of management. However, curren
Product details
The ZY-LLJLY-100 series flow recorder is a high-speed and high-performance microprocessor with a 5.6-inch monochrome LCD display screen, which can monitor, control, and record various signals such as temperature, pressure, flow, and electricity on site.
The ZY-LLJLY-100 series flow recorder can freely configure input signals such as standard current, standard voltage, thermocouple, thermistor, frequency, etc. It can be used for sensor distribution and relay alarm output, and can exchange data with the upper computer through USB or communication methods. The paperless recorder itself has real-time data display screen, curve display screen, and bar chart data display screen. At the same time, it can be connected to a micro printer to achieve on-site printing function, and connected to an audible and visual alarm to achieve on-site audible and visual alarm function.
The ZY-LLJLY-100 series flow recorder is a signal input that can record all on-site signals such as temperature, temperature and humidity, current, voltage, pressure, flow rate, liquid level, etc.
The ZY-LLJLY-100 series flow recorder is currently mainly used in various industrial fields such as metallurgy, petroleum, chemical, building materials, papermaking, food, pharmaceuticals, heat treatment, water treatment, etc. It is a new generation of economical and practical paperless recorders that replace traditional recorders.
The combination of recorder and on-site instruments:
1. Install a flow meter to measure and record on-site flow signals.
2. Equipped with a pressure transmitter to measure and record pressure signals on site.
3. Equipped with temperature sensors to measure and record temperature signals on site.
4. Distribution quantity transmitter, capable of measuring and recording on-site electrical signals.
5. Equipped with a liquid level transmitter to measure and record on-site liquid level signals.
6. Install a temperature and humidity transmitter to measure and record temperature and humidity signals on site.
