Editor’s choice TITAN’S BEVERAGE W MATERIALS & DESIGN:
Turbine Meter: Constructed from PVDF with sapphire bearings and Viton seals, it is robust and resistant to a wide temperature range. This device is NSF-approved under the NSF standard 169 as ‘Special Purpose Food Equipment and Devices’.
Ultrasonic Meter: Built from food approved ABS/PC polymer with Viton seals, offering a lightweight design with a straight 6 mm bore. The absence of internal obstructions makes it easy to clean using sponge balls. All parts are to FDA / EU food approved standards and NSF-approval will be sought for this product when it reaches full commercialisation.
FLOW METERS: TURBINE VS. ULTRASONIC – WHICH IS RIGHT FOR YOU?
hen it comes to beverage dispensing and flow measurement, Titan Enterprises offers two distinct solutions: the well-
established Beverage Turbine Meter and the newly released Ultrasonic Beverage Meter. Each has unique strengths and trade-offs, making the choice application-dependent.
Here we define the differences between the technologies used within each Beverage flow meter:
MEASUREMENT TECHNOLOGY:
Turbine Meter: Operates on a mechanical principle using a Pelton wheel turbine and sapphire bearings. This design provides consistent repeatability and has 1.5 per cent Full Scale Accuracy but introduces moving parts into the system.
Ultrasonic Meter: Uses the ‘time of flight’ principle to measure flow, with no moving parts. This eliminates mechanical wear and contamination risk, while offering a completely clean, straight bore, and accuracy better than two per cent of reading.
PERFORMANCE: Granularity:
Beverage Turbine: 1,400 pulses per litre (lower resolution).
Ultrasonic Beverage: 5,000 pulses per litre (higher resolution).
Flow Range:
Beverage Turbine: 0.6–10 l/min - limited low-end capability.
Ultrasonic Beverage: 0.2–10 l/min - better for low flow applications.
Linearity & Repeatability:
Beverage Turbine: ±1.0% FSD linearity, excellent ±0.1% repeatability.
Ultrasonic Beverage: ±2% of reading linearity, ±0.5% repeatability.
Temperature Range:
Beverage Turbine: 0–125 °C, suitable for hot and cold beverages.
Ultrasonic Beverage: 3–15 °C, restricted primarily to chilled beverages.
INSTALLATION & OPERATION:
Both beverage meters use John Guest 3/8” push-fit connections, ensuring compatibility with standard tubing.
Pressure drop is minimised in both designs, though the ultrasonic’s straight 6mm bore gives it a lower overall pressure drop.
Power requirements differ slightly: the beverage turbine meter runs from 5–24 VDC, whereas the ultrasonic models require 7–24 VDC.
Both types are calibrated in-situ by the customer to suit the system requirements.
No moving parts within the ultrasonic beverage meter eliminates any contamination issues and allows the use of sponge balls to clean.
COST CONSIDERATIONS:
Beverage Turbine: Budget-friendly and reliable, particularly for high-temperature or mixed-use applications.
Ultrasonic Beverage: Nearly five times the cost, but justifiable for hygienic, low-maintenance, and high-resolution needs.
