Sanitary Coriolis Flow Meter

A sanitary Coriolis flow meter measures mass flow directly from the Coriolis force on a vibrating measuring tube, with density and medium temperature derived on the same loop. The sanitary form factor packages those measuring tubes inside a polishable 316L hygienic body with Triclamp hoop-clamp process connections and ferrule sealing for tool-free CIP disconnect. Direct mass flow is the headline benefit for brewery, dairy, and pharmaceutical service; volumetric meters need a separate density input to convert liters into kilograms, while Coriolis reads kg/h on the 4-20 mA loop with no inferred input. The density channel doubles as a Brix or Plato indicator for brewery wort and beverage sugar tracking.

Triclamp for any line that opens for cleaning validation, gasket inspection, or batch changeover; brewery wort kettle outlet, bright-tank transfer, dairy milk reception, cream separator outlet, pharmaceutical batch reactor outlet, formulation vessel discharge. The 1.5″, 2″, 3″, and 4″ Triclamp hoop-clamps mate directly with brewery and dairy plant piping and give tool-free disassembly. Flanged is the right pick for fixed installs that do not open between CIP cycles; utility headers, CIP solution distribution loops, and pump-discharge measurement points that stay in service. For mixed-service skids, specify Triclamp on the process side and flanged on the utility side at order.

The standard build covers CIP cleaning at typical brewery and dairy cycle temperatures; hot-water rinse, caustic 2 to 5% NaOH at +85 °C, acid CIP, and sanitizer ringing. The −20 to +150 °C medium temperature range also covers SIP (steam-in-place) at +150 °C as a transient cleaning step. The Triclamp hoop-clamp connection allows quick disassembly for gasket inspection between batch changeovers, and the polishable 316L wetted-parts surface minimizes microbial holdup. Note: the meter measures the CIP solvent flow during the cleaning cycle itself, not just product flow; a useful side benefit for CIP recipe verification. Re-zero the meter at process temperature after each CIP cycle for the tightest measurement accuracy.

The factory ships polishable 316L wetted parts, hoop-clamp Triclamp process connections with ferrule sealing, and a CIP-compatible build geometry; the physical build for sanitary service. What ships standard with every meter: 316L mill certificate traceable to heat number, polish-grade sign-off per the order spec (Ra typically 0.4 to 0.8 µm, buyer specifies the range), and the ISO 9001 K-factor calibration certificate. Sanitary type-approval certification per the local regulatory regime; whether that is the US dairy market regime, the EU food market regime, US pharmaceutical service review, or the local equivalent; is buyer-arranged with a notified body. The factory build documentation supports that submission; the certification itself is not held ex-factory. For regulated facilities, engage with the engineering team at quote stage so the build documentation matches the buyer’s audit regime.

The Coriolis tube vibrates at a resonant frequency that shifts with fluid density on the same tube that measures mass flow; so a single meter reads mass flow, volumetric flow, density, and medium temperature simultaneously. Brewery and beverage operators use the density channel to derive degrees-Brix (sugar content in syrup, fruit juice, and wort) and degrees-Plato (extract content in beer wort) directly on the 4-20 mA loop or HART, without a separate refractometer or hydrometer at the measurement point. Density accuracy is ±0.002 g/cm³ across the 0.3 to 3.000 g/cm³ range, which is finer than the typical ±0.1 Brix industrial requirement on wort kettle and bright-tank transfer. Density data also gives dairy operators a fat-content indicator on cream-separator outlet and supports concentration tracking on cosmetics emulsion and fine-chemical batch dosing.

Lead time is 5 to 7 business days from order confirmation, factory direct. Each meter ships with the ISO 9001 K-factor calibration certificate, the 316L mill certificate traceable to heat number, and the polish-grade sign-off per the order spec. Hygienic features that ship standard: Triclamp hoop-clamp process connection in 1.5″ / 2″ / 3″ / 4″ with ferrule sealing, polishable 316L wetted parts (Ra typically 0.4 to 0.8 µm as specified at order), CIP-compatible build for brewery and dairy cleaning recipes, and SIP capability to +150 °C transient. Ex d [ia] IIC T6 Gb is standard for hazardous-area service (combined flameproof + intrinsically safe), with a Non-Ex option for general-purpose installs. IP67. The buyer-arranged sanitary type-approval pathway is documented in the engineering review at quote stage.
