-Overview-
This MDS-6300A online viscometer is suitable for real-time monitoring and control of liquid viscosity in industrial production processes. The instrument operates based on the principle of vibration, measuring viscosity by detecting changes in the amplitude of a cone vibrating within the liquid, and features temperature compensation to improve measurement stability.
This viscometer is primarily used for process measurements in the chemical industry, including paint, crude oil, dairy products, and adhesives. Its design supports multiple installation methods, including pipeline installation and tank side mounting, and is compatible with flange or clamp connections to meet various operating conditions.
The product features a 4-20mA signal output and RS485 communication capability, enabling remote data transmission and system integration. Users can easily set and adjust on-site parameters via the instrument's built-in buttons and menus, including range, unit, fine-tuning of measured values, and damping adjustment. The instrument has a robust structure, with the liquid-contacting parts made of stainless steel, making it suitable for general industrial media environments. During installation, care should be taken to avoid interference factors such as vibration, air bubbles, and media crystallization to ensure long-term stable operation.
