APPLICATION DECISIONS
Engineering logic for the measurement point
Start with the product and cleaning recipe. State viscosity, solids, fat or sugar content, conductivity, density, foam, aeration, coating and phase changes across production. Add cleaning chemicals, concentration, duration, temperature and pressure, including rapid transitions. A sensor that measures the product must also tolerate the cleaning sequence. Wetted metals, elastomers, liners, electrodes, diaphragms and fill fluids require review against both conditions.
The process connection is an engineered interface. Identify the plant standard, nominal size, mating geometry, gasket, orientation and drainability requirement. A flush diaphragm can reduce an exposed passage but does not by itself prove cleanability or hygienic status. Level selection also depends on vessel internals, agitators, foam and density; flow selection depends on conductivity, viscosity, bubbles, pipe profile and minimum rate. Temperature assemblies require insertion and thermowell review.
Document control supports plant acceptance. State which connection drawing, material declaration, surface record, elastomer information, calibration document or applicable certificate is required. Verify that each document covers the model, connection and options being ordered. The website does not treat a food-grade phrase as evidence for every variant. Final selection should include installation, cleaning, commissioning and maintenance instructions appropriate to the actual measurement point.
Measurement and engineering factors
- Product properties
- Provide composition, viscosity, density, conductivity, solids, foam, aeration, coating, temperature and product-change conditions.
- Hygienic interface
- Specify connection standard and size, mating geometry, gasket or elastomer, installation orientation, drainability and dead-space restrictions.
- Cleaning cycle
- List chemicals, concentration, temperature, pressure, duration, frequency, rinse and sterilisation conditions where applicable.
- Measurement and integration
- Define variable, range, response, power, output, display, control-system connection and maintenance access.
- Evidence requirements
- Name the material, surface, elastomer, calibration, drawing or approval documents required for the exact configuration.
Application scenarios for review
- Mixing and storage vessels where product coating, foam, agitation, cleaning and connection geometry are available for level or pressure review.
- Product and ingredient lines where conductivity, viscosity, bubbles, minimum flow, cleaning and allowable pressure loss support flow sizing.
- Pasteurisation, heating, cooling and utility systems where sensor insertion, temperature cycles and process-boundary materials are specified.
Limitations and confirmation points
- A sanitary appearance, clamp connection or flush diaphragm does not prove cleanability, drainability, food-contact compliance or approval coverage.
- Changing recipes, aeration, coating, high viscosity and rapid cleaning cycles may require application trials or design review beyond catalogue comparison.

APPLICATION FAQ
Frequently asked questions
What makes a process connection suitable for hygienic review?
The connection must be evaluated as a complete mating assembly: instrument geometry, plant ferrule or socket, gasket, wetted materials, surface condition, orientation and drainability. Provide the exact standard, size and installation drawing plus the cleaning procedure. A familiar clamp shape is not sufficient evidence. Request the drawings and records required by the facility, then verify that their scope covers the selected model, connection and seal arrangement before approval.
Why must cleaning conditions be included with normal process data?
Cleaning or sterilisation may expose the instrument to different chemicals, higher temperature, pressure, vacuum or faster thermal transitions than production. Those conditions affect wetted materials, elastomers, fill systems, electronics isolation and measurement recovery. List every cleaning chemical and concentration, maximum values, duration, frequency and whether the instrument stays installed and powered. The complete cycle should be checked against the exact configuration rather than assuming normal product temperature is the limiting case.
How do product properties affect flow-meter selection?
Conductivity is relevant to electromagnetic measurement; viscosity and cleanliness influence turbine applications; bubbles, suspended solids, coating and changing recipes can affect several principles. Minimum, normal and maximum flow, pipe dimensions, pressure, temperature and allowable pressure loss are also needed. For batching, define the control objective and valve sequence. A sizing response should record all inputs and identify the proposed meter configuration instead of promising one technology for every beverage or ingredient.
