Technical details and manufacturing context for Sanitary Flow Meter

Definition
Within an Automated Beverage Batch Blending System, the sanitary flow meter is a critical measurement component that accurately monitors the flow rate of various liquid ingredients (water, syrups, concentrates, additives) as they are precisely dosed and blended according to recipe formulations. It ensures consistent product quality, batch-to-batch repeatability, and process efficiency by providing real-time feedback to the system's programmable logic controller (PLC) for automated control and verification. The meter is designed for hygienic applications, with wetted parts made of 316L stainless steel, PTFE, and FDA-compliant elastomers, featuring polished, crevice-free surfaces and sanitary connections (clamp, flange, or thread) to facilitate cleaning-in-place (CIP) and sterilization-in-place (SIP) without disassembly. It operates on principles such as electromagnetic induction for conductive liquids, Coriolis force for mass flow and density measurement, or positive displacement, depending on the model. Key parameters include a flow rate range of 0.5–100 L/min, accuracy of ±0.5% of reading, operating pressure of 1.0–1.6 MPa, operating temperature of -40–85°C, ambient humidity of 0–95% RH (non-condensing), ingress protection of IP65–IP67 (per IEC 60529), supply voltage of 24 ±10% V DC (optional 230 V AC), output signal of 4–20 mA with HART, pulse, or Modbus, process connection sizes of DN15–DN100 (per ISO 2852), and weight of 2.5–15 kg. These values are reference ranges and must be verified for the specific model and application with the legal manufacturer or supplier. The meter provides real-time data essential for automated control, ensuring precise dosing and blending, and supports verification of process conditions and maintenance needs.
Working Principle
The sanitary flow meter measures liquid flow using one of several principles. Electromagnetic meters use Faraday's law of induction, requiring conductive liquids, and generate a voltage proportional to flow velocity. Coriolis meters measure mass flow and density by detecting phase shifts in vibrating tubes. Positive displacement meters trap and count discrete volumes. In sanitary designs, wetted parts are polished and crevice-free, often 316L stainless steel, with PTFE or FDA-compliant elastomers, and use sanitary fittings like tri-clamp connections to allow complete CIP and SIP without disassembly.
