Flow Measurement Solutions for Food & Beverage Industry

Milk, juice, water, beer, and sauces are water-based and conductive — magnetic flowmeters measure them with zero obstruction. Edible oils, ethanol, spirits, and pure syrups are non-conductive — magnetic meters produce no signal at all. A facility handling both fluid types requires two different meter technologies on the same production floor.

Process water runs at under 1 cP. Glucose syrup at 20°C can exceed 1,000 cP. High-fructose corn syrup reaches 5,000 cP. Vortex and turbine meters lose accuracy sharply as viscosity rises — their shedding frequency and rotor speed both respond poorly to thick fluids. Magnetic meters remain accurate regardless of viscosity. Coriolis meters measure directly by mass, making them viscosity-immune and ideal for high-value syrup dosing where density also matters.

Flowmeter with internal crevices, gasket recesses, or non-drainable geometries trap product and resist CIP cleaning. HBYB hygienic-series meters use smooth-bore interiors, fully drainable sensor bodies, and tri-clamp connections designed to be completely swept by cleaning solution. The same principle applies to connection type: a threaded port in a sanitary line is a bacterial growth site that tri-clamp connections eliminate by design.

For ingredient dosing and batching, the critical metric is repeatability — — that each shot delivers exactly the same volume — not just average accuracy. A meter with ±0.5% accuracy but ±0.3% repeatability is worse for batching than a meter with ±1.0% accuracy and ±0.1% repeatability.. A turbine meter's high-frequency volumetric pulse output makes it the standard choice for batching non-conductive liquids (oils, ethanol). For the highest-value batching applications — concentrates, flavor extracts, pharmaceutical-grade ingredients — Coriolis mass meters offer both direct mass output and density measurement in one instrument, eliminating the need for separate density checks.

CO₂ for carbonation and N₂ for blanketing must be measured as mass flow (kg/h or Nm³/h), not volume — because gas volume changes with pressure and temperature while mass does not. Thermal mass flowmeters deliver direct mass output without any additional transmitters or flow computers. A volumetric meter on a CO₂ line will give different readings at the same actual mass flow depending on ambient temperature — an invisible source of carbonation inconsistency.

Pasteurization uses saturated steam at 130–145°C; UHT sterilization and SIP use superheated steam at up to 180°C. Turbine bearings fail under thermal shock. Differential pressure meters require impulse lines that are a maintenance burden in steam environments. Vortex meters — with no moving parts in the flow path — are the industry standard for food-grade steam measurement, operating reliably up to 350°C with no scheduled maintenance on the flow element.
