YMF886 Tuning Fork Density Meter
The YMF886 Tuning Fork Density Meter is an advanced industrial instrument designed for continuous, real-time density measurement of liquids in various process conditions. Utilizing vibration frequency tracking technology, it features a robust tuning fork sensor that vibrates at a natural frequency proportional to the density of the medium. This model is engineered for insertion-based installation, making it suitable for pipelines, open tanks, and closed containers. With high accuracy (up to ±0.001 g/cm³) and minimal influence from temperature, pressure, or flow variations, it is ideal for applications in mining, chemical processing, power generation, and food production.
