Food & beverage covers beer, wine, spirits, sugar, condiments, dairy, vegetable oil, juices. Sanitary standards are uniform, but medium characteristics — color, bubbles, suspended particles — drive principle choice.
Food & Brewing Density Meter Selection Guide
Food and brewing applications require both sanitary-grade compliance and matching the medium's unique character (color / bubbles / particulates). This guide breaks recommendations down by food category.
Steps
-
Brewing (bubbles + dark)
Fermenting wort with dark color + high gas content is a refractometer nightmare. Strongly recommend PS7020 sound velocity (color / bubble-immune). Brix accuracy ±0.5‰; tracks the full fermentation curve online. -
Spirits / yellow wine (alcohol + sugar)
Alcohol (ethanol) and residual sugar — two components simultaneously. Recommended PS7100 spectroscopy (MLR dual-component) or PS7020 sound velocity (single-component high-accuracy). -
Sugar refining (high Brix + crystals)
Sugar evaporator-crystallizer Brix monitoring. Recommended PS7110 refractometer (sapphire prism withstands crystal abrasion), self-cleaning at high flow; low flow takes the optional CYR-Wiper pneumatic brush. -
Condiments (soy sauce / vinegar / fish sauce)
Dark + light suspended particulate. Recommended PS7020 sound velocity. A soy sauce factory replaced lab sampling with PS7020 for continuous Baume monitoring. -
Beverages / juice (with pulp particles)
High-fiber + particulate content clogs narrow flow paths. Recommended PS7400 (sanitary clamp + PTFE coating) or PS7210 Coriolis (sanitary clamp). -
Dairy (strict CIP / SIP)
High-temp sterilization + frequent chemical cleaning. Recommended PS7400 (PTFE-coated) or PS7210 Coriolis (sanitary clamp). Both withstand 134°C steam, 3% NaOH / 3% HNO3 CIP. -
Vegetable / edible oils (custody transfer)
Finished blended oil / palm oil / soybean oil custody metering. Recommended PS7400 + temperature compensation; OIML R117 certified version available for trade settlement.
