Process Instrumentation for the Food & Beverage Industry
A complete portfolio of hygienic instruments for pressure, temperature, flow, level, and analytical measurement enables accurate, reliable, and traceable performance across food and beverage processes.Designed for sanitary compliance and precision control, the systems ensure process stability, repeatability, and full CIP/SIP compatibility under demanding production conditions.
Addressing the Core Challenges of Food & Beverage Process Control
Food and beverage production involves strict hygiene requirements, dynamic process parameters, and demanding traceability standards. Advanced instrumentation ensures measurement integrity, corrosion resistance, and intelligent connectivity for stable and compliant operations.
Hygienic Measurement under CIP/SIP Conditions
Sanitary pressure and temperature transmitters withstand high-temperature, high-pressure cleaning cycles, ensuring accurate and contamination-free measurement during automated CIP/SIP operations.
Wide Process Range and Dynamic Loads
Processes such as pasteurisation, carbonation, and fermentation involve large variations in temperature and pressure. Instruments maintain accuracy across these ranges through robust mounting, fast response, and built-in diagnostics.
Precision in Flow and Level Control
During mixing, filling, and dosing, flow and level transmitters provide stable hygienic signals integrated into SCADA systems, ensuring recipe consistency and minimising waste.
Data Integration and Traceability
Modern transmitters support HART and Modbus communication, asset diagnostics, and digital traceability — enabling full compliance with food safety and quality standards.
Instrumentation Across Food & Beverage Applications
Hygienic instrumentation supports reliable measurement and process control across every sub-sector of food and beverage production.
Carbonated Beverages
Soft-drink production requires precise carbonation, stable pressure control, and cleanability. Sanitary transmitters and flow meters maintain consistent operation and compliance with wash-down standards.
Fruit Juice Processing
Juice extraction and blending involve variable viscosity, foaming, and high-temperature cleaning. Flow and level sensors ensure accurate dosing and easy maintenance under hygienic conditions.
Food Processing & Ready-to-Eat Production
Ready-to-eat food lines combine cooking, mixing, and packaging under strict hygiene and traceability requirements. Reliable pressure, temperature, and flow measurement ensures consistent quality and safety compliance.
Pasteurised & UHT Milk
Pasteurisation and UHT lines require tight temperature regulation and aseptic integrity. Stainless-steel transmitters ensure accurate thermal control and long-term calibration stability.
Yogurt & Fermented Dairy
Fermentation and filling systems require precise level and flow monitoring despite changing viscosity. Hygienic sensors minimise dead zones and ensure repeatable, contamination-free measurement.
CIP/SIP Cleaning Systems
Cleaning and sterilisation cycles expose instruments to extreme heat and chemicals. Stainless-steel sensors with hygienic fittings withstand repeated wash-downs while providing diagnostic feedback for predictive maintenance.
Beer & Brewing
Fermentation, maturation, and carbonation demand reliable temperature and pressure control. Hygienic transmitters and level instruments deliver process stability and repeatable performance under CIP/SIP conditions.
Process Flow and Instrumentation Layout in the Food & Beverage Industry
From raw material intake to final packaging, instrumentation ensures precise measurement of pressure, temperature, flow, level, and analytical parameters—maintaining process safety, stability, and full traceability throughout production.

Real-World Instrumentation Cases in the Food & Beverage Industry
These cases demonstrate the performance of our instrumentation in real food and beverage plants—delivering reliable measurement, enhanced process control, and full traceability.
Carbonated Soft-Drink Line Pressure & Flow Stabilisation
Challenge:
A beverage plant faced pressure fluctuations in the carbonation vessel and unstable filling-line flow, causing density variation and line stoppages. Existing pressure sensors drifted after wash-downs, and flow meters lacked diagnostics.
Solution:
A hygienic pressure transmitter with stainless-steel diaphragm and IP69K protection, combined with a sanitary electromagnetic flow meter with HART diagnostics, was integrated into the PLC network for real-time monitoring and predictive maintenance.
Result:
Pressure stability improved by 45%, unplanned downtime reduced by 30%, and filling consistency met quality specifications.
UHT Milk Pasteuriser Temperature & Level Measurement
Challenge:
Precise temperature and level control were required under high-temperature CIP/SIP conditions. Previous sensors lacked self-verification and required frequent recalibration.
Solution:
A hygienic temperature transmitter with built-in reference verification and an 80 GHz radar level transmitter were installed using Tri-Clamp fittings and Modbus communication. Foam suppression and condensation-resistant design ensured reliable performance in hot, humid environments.
Result:
Calibration intervals extended by 40%, level accuracy improved to ±0.5%, and the plant achieved automated overnight operation with full SCADA traceability.
Yogurt Fermentation Vessel Flow & Analysis Control
Challenge:
Fermentation control required accurate flow, pH, and density measurement under vibration and wash-down conditions.
Solution:
A sanitary electromagnetic flow meter, automatic-cleaning pH analyzer, and multiparameter analyzer (pH, conductivity, temperature) were integrated via HART protocol with the plant MES.
Result:
Inoculant dosing accuracy improved by 25%, fermentation cycle time reduced by 15 minutes, and vibration-induced signal drift was virtually eliminated.
