LWGY Liquid Turbine Flow Meter; instrument body with display head

Sanitary turbine flow meters play a key role in non-conductive food, beverage, and pharmaceutical fluid metering; ethanol CIP, USP-grade purified water, glycerine, glucose syrup, and pharma solvents below the EMF 5 µS/cm floor. The LWGY covers Line sizes 1/2″ to 4″ (DN15 to DN100) with 316L electropolished body to Ra ≤ 0.4 µm and sanitary Tri-clamp connection. High-temperature type required for SIP at +121 °C; room-temperature type covers CIP at +85 °C.

Benefits

  • Measures non-conductive sanitary fluids below EMF 5 µS/cm floor
  • Accuracy +/- 0.5% of rate
  • Sanitary Tri-clamp connection standard
  • 316L electropolished body to Ra ≤ 0.4 µm
  • SIP +121 °C compatible (high-temperature type)
  • Pulse output for batch-dosing controllers

Typical applications

Four sanitary applications for fluids EMF cannot read.

💊

Pharmaceutical purified water polishing loop

USP-grade DI water polishing loops; DI sits below EMF 5 µS/cm floor. 316L electropolished Ra ≤0.4 µm; Tri-clamp for clean-disconnect.

🧬

Ethanol-based CIP and SIP circuit metering

CIP circuits use ethanol/IPA at 1.2 cSt; EMF can’t read. LWGY tracks solvent per cycle; high-temp type covers SIP +121°C transient.

🍿

Beverage glucose syrup and concentrate batching

Glucose syrup, fructose, warm sugar (5–8 cSt warm) sit inside range. Pulse drives recipe controller for preset cutoff; ±0.5% rate for formulation.

🍼

Pharmaceutical solvent and intermediate dosing

Pharma reactors dose non-conductive solvents (ethanol, methanol, IPA, recovered acetone). Tri-clamp for deep cleaning; 316L + duplex impeller for reactor chemistry.

Installation

Key install requirements. Full datasheet on request.

  • Run pipe full at the meter; pump-discharge or pressurised batch-feed leg only
  • Use EPDM Tri-clamp gaskets standard; PTFE upgrade for aromatic solvent service
  • Maintain ≥ 10 D upstream and ≥ 5 D downstream straight pipe
  • Slow-fill on first commissioning and after every CIP cycle
  • Inspect impeller every 6 months via Tri-clamp disconnect

Frequently asked questions

What is a sanitary turbine flow meter and how does it work?+
A sanitary turbine flow meter measures volumetric flow of non-conductive food, beverage, or pharmaceutical fluid through a free-spinning rotor. The 316L electropolished body with sanitary Tri-clamp connection supports CIP (clean-in-place) and SIP (steam-in-place at +121 °C) cleaning cycles between batches. The build targets non-conductive sanitary fluids EMF cannot measure.
When does sanitary turbine beat sanitary EMF?+
Sanitary EMF (LEA with PFA liner) is the pick for conductive sanitary fluids; milk, juice, beer wort, brine; above the 5 µS/cm floor. Sanitary turbine handles non-conductive fluids EMF cannot measure: ethanol CIP, USP-grade purified water, glycerine, light vegetable oil warm, glucose syrup, and pharma solvents below 10 cSt. Turbine pulse output also integrates more directly with batch-dosing controllers.
What sanitary fluids fall outside the LWGY range?+
Cold viscous syrup, honey, molasses, and cold vegetable oil above 10 cSt; warm-operation only or go to Coriolis for ambient service. Yogurt, cream, fruit purée, and other shear-thinning fluids damage the rotor; go to LEA sanitary EMF with PFA liner. Ice cream mix and non-Newtonian flows bias the K-factor; go to Coriolis. Steam SIP is transient cleaning service only, not continuous service.
What pipe sizes and connections fit sanitary process skids?+
DN15 to DN50 covers pharmaceutical purified water polishing, ethanol CIP circuits, and small batch reactor feed lines. DN65 to DN100 covers larger batch reactor headers, beverage glucose syrup batching, and inter-tank transfer lines. Sanitary Tri-clamp is standard for hygienic clean-disconnect; threaded connection is available for fixed-install measurement points. The 316L electropolished body to Ra ≤ 0.4 µm supports CIP and SIP cleanability.
Does the meter handle CIP and SIP cleaning cycles?+
Yes; high-temperature type (Temperature Application -40 to +180 °C) covers SIP at +121 °C; room-temperature type covers CIP at +85 °C. Tri-clamp connection allows quick clean-disconnect; electropolished surface minimizes microbial holdup. 316L body and duplex impeller handle ethanol CIP and caustic CIP detergent (NaOH 2 to 5% at +85 °C). Note: the meter measures the CIP solvent flow itself; SIP steam is transient cleaning service only.
How does pulse output integrate with batch-dosing controllers?+
The 3-wire pulse output is frequency-proportional to flow with the calibrated K-factor on each meter’s certificate. Sanitary process controllers (Allen-Bradley PLC, Siemens S7) accept the K-factor at recipe programming and convert pulses to liters or kilograms on the recipe display. Beverage glucose syrup batching, pharmaceutical purified water draw-off, and ethanol CIP circuit recharging all use pulse output for preset-volume cutoff. RS-485 Modbus and HART are also available.
What is the lead time and what hygienic features ship standard?+
Lead time is 5–7 business days from order confirmation, factory direct. Each meter ships with an ISO 9001 calibration certificate listing K-factor, calibrated DN, and tested flow range. Hygienic features that ship standard: sanitary Tri-clamp connection, 316L body with electropolished surface to Ra ≤ 0.4 µm, CIP / SIP cleanability. EMC 2014/30/EU and IP65 / IP66 / IP67 are selectable. JB/T9246-2016 is the underlying standard.
