Precision Coriolis Mass Flow Measurement for Ammonia Industrial Applications

 

Ammonia is one of the most challenging fluids to measure in industrial processes. It is flammable, explosive, toxic, and highly corrosive. It vaporizes easily, frequently creating gas-liquid two-phase flow conditions. Its density shifts dramatically with changes in temperature and pressure. These harsh characteristics make accurate and reliable flow measurement a significant engineering challenge.

 

Standard flow meters often fail in ammonia service. They are prone to corrosion, inaccurate readings during two-phase flow, and unsafe operation in hazardous environments. That is why engineers and plant managers turn to Coriolis mass flow meters – the only technology that delivers direct mass measurement independent of temperature, pressure, density, or flow regime.

 

Why Coriolis for Ammonia?

 

Coriolis mass flow meters measure mass flow directly, not volumetric flow. This means they provide accurate readings regardless of pressure fluctuations or temperature changes – common conditions in ammonia refrigeration, storage, and transport. They also handle gas-liquid two-phase flow better than most other technologies, maintaining measurement stability even when flash vaporization occurs.

 

Key Applications

 

Ammonia is used across a wide range of industries, and our Coriolis meters are deployed in the most demanding scenarios:

 

Ammonia Refrigeration Systems – The largest and most critical application. In cold storage warehouses, food processing plants, and seafood quick-freezing facilities, our meters monitor liquid ammonia flow, calculate cooling capacity, detect leaks, and support overall system safety management.

 

Chemical Synthesis – From urea and compound fertilizer production to ammonium hydroxide preparation, precise ammonia feeding is essential. Our meters ensure accurate dosing for SCR denitrification and ammonia slip control in flue gas treatment.

 

Tanker Loading and Custody Transfer – When liquid ammonia is loaded or unloaded from tankers, mass-based trade settlement is the only fair and accurate method. Our meters provide direct net weight measurement, unaffected by temperature or pressure, ensuring transparent and dispute-free transactions.

 

Power Plant Denitrification – In boiler flue gas treatment, our meters control ammonia water blending and precise injection, supporting environmental compliance and reducing ammonia slip.

 

Pharmaceutical and Chemical Fiber Production – From nylon fiber manufacturing to amine-based chemical synthesis, precision metering in process pipelines is critical. Our meters deliver the accuracy that high-value chemical reactions demand.
