Coolant Concentration Meter Inline

Short Description:

An inline coolant concentration meter is an automated instrument to measure concentration in real-time monitoring of the concentration of key components in coolants. It is widely used in industries where precise control of coolant performance is required. It utilizes acoustic signals to excite the tuning fork to vibrate, thereby measuring the concentration of the coolant (such as the concentration of emulsion in cutting fluids, or the concentration related to the freezing point/boiling point of antifreeze) in real-time. The collected data is then fed back to the control system to enable automatic adjustment or manual intervention, ensuring production efficiency, equipment lifespan, and product quality.

    Product Tags

    In metal cutting, grinding, stamping and other processing procedures, the concentration of coolants (such as cutting fluids, emulsions, oil - based coolants) directly affects lubrication, cooling, rust - prevention and chip removal effects, serving as a core parameter to ensure processing quality and equipment safety. The inline coolant concentration meter is equipped with a coolant concentration sensor resistant to the corrosion of various coolants. As a crucial inline process instrument, it enables real - time and accurate monitoring of coolant concentration. Its advantages of easy operation, high precision and efficient performance make it an ideal inline tool in multiple industrial applications.

    Working Principle

    It utilizes an acoustic signal source to excite a metal tuning fork, causing it to vibrate at its inherent resonant frequency. This resonant frequency has a direct correlation with the density of the coolant in contact with the tuning fork during the machining process. By conducting frequency analysis of the vibrating tuning fork, the instrument can accurately measure the density of the coolant (such as cutting fluids, emulsions, or oil - based coolants) circulating in the processing system.

    Advanced signal processing algorithms;
    Versatile measurement capabilities;
    Fast response for timely adjustment and human intervention;
    Support integration with PLC/DCS control system;
    Explosion-proof and waterproof design;
    Intuitive interface and simple mechanical structure
    Data logging and documentation functions.

    Application

    Some industrial plants or manufacturing facilities could benefit from the inline coolant concentration meter:​
    Metal processing factories for cutting and grinding processes to monitor the concentration of emulsion in cutting fluids, ensuring stable lubrication, cooling and rust - prevention performance and reducing tool wear;​
    Automobile manufacturing plants for engine and transmission processing lines to keep the coolant concentration within the optimal range, protecting components from overheating or corrosion during processing and testing;​
    Industrial refrigeration plants for glycol cooling systems to monitor the continuous concentration of glycol solution, balancing antifreeze effect and heat transfer efficiency and preventing pipeline freezing or energy waste;​
    Chemical production plants for reactor cooling circuits to maintain the stable concentration of cooling fluids, ensuring precise temperature control during chemical reactions and improving product quality stability;​
    Shipbuilding yards for marine engine cooling systems to monitor the concentration of ethylene glycol and corrosion inhibitors in coolants, protecting engines from freezing in low - temperature navigation and reducing seawater corrosion.
