The gamma radiation source (60Co) has high penetrating energy, making it particularly suitable for level measurement in thick-walled, high-pressure tanks, as well as density measurement in large-diameter pipes and over large measuring ranges.
Benefits
The point source is placed in a special source capsule, ensuring simple handling and installation.
Special source capsule design meeting the strictest safety requirements: typical category C66646, in accordance with ISO 2919
The activity of the source can be selected to suit your application requirements, ensuring the optimum dose
Applications
Radioactive isotopes are used as gamma radiation sources for level, density and interface measurement as well as limit detection. A gamma source radiates equally in all directions, but in radiometric measurement only the radiation passing through the tank area or pipe is used as effective radiation; all other radiation is redundant and must be shielded.

Municipal Wastewater Treatment · radiant — Application Case
Site Conditions
This is a Municipal Wastewater Treatment customer whose plant is at the inlet, biological and outlet stages of a municipal plant. The main task was non-contact level measurement in extreme duty using radiometric principles.
The Problem
The difficulty lies in high solids and corrosive fractions, with large diurnal flow swings; at the same time effluent parameters drift and probes foul with sludge and biofilm. Specification therefore means sizing source strength against wall thickness, density and licensing requirements.
What We Did
We took a level range approach — level solution matched to the actual tank and silo geometry. Delivery was built around sizing source strength against wall thickness, density and licensing requirements, with point-by-point checks on: stable compliance with Grade 1A discharge limits and online data reporting.
Operating Outcome
In service the system performs as intended — measurable under high temperature, pressure and corrosion without intruding into the vessel, with routine maintenance falling noticeably.
Food & Beverage · radiant — Application Case
Application Context
dosing, pasteurising, filling and CIP stages is a typical Food & Beverage duty. The project started from radiant, focusing on non-contact level measurement in extreme duty using radiometric principles.
Process Constraints
frequent cleaning demands instruments that withstand hot CIP/SIP caustic cycles, and syrups, dairy and beverages that scale easily, under strict hygienic requirements only amplify it. The radiant specification must therefore cover sizing source strength against wall thickness, density and licensing requirements.
Delivery Approach
Delivery was handled as the level range — level solution matched to the actual tank and silo geometry. Execution centred on sizing source strength against wall thickness, density and licensing requirements, together with food-safety and hygienic design per 3-A / EHEDG.
Field Results
Operation shows the benefit clearly — measurable under high temperature, pressure and corrosion without intruding into the vessel, with confidence in this measuring point improving markedly.
Chemical & Pharmaceutical · radiant — Application Case
Customer Profile
The typical setting in Chemical & Pharmaceutical is reactors, metering vessels and finished-product tanks. The measuring point is radiant; the focus is non-contact level measurement in extreme duty using radiometric principles.
Key Difficulties
Conditions are highly corrosive media with solvents and crystallisation, partly in explosive atmospheres and, on top of that, corrosion plus Ex protection shortens instrument life and makes downtime costly, which a standard configuration cannot handle for long. The design therefore starts with sizing source strength against wall thickness, density and licensing requirements.
Implementation
The scope ran through the level range: level solution matched to the actual tank and silo geometry. Technically it hinges on sizing source strength against wall thickness, density and licensing requirements, and on these requirements: Ex certification and GMP traceability of records.
Customer Benefit
In practice this means measurable under high temperature, pressure and corrosion without intruding into the vessel, which cut the workload on the site maintenance team.
Power & Energy · radiant — Application Case
Project Background
The project covers boiler feedwater, turbine condensate and FGD/DeNOx systems. The work centres on radiant and the core task is non-contact level measurement in extreme duty using radiometric principles.
Operating Challenges
The medium and duty are characterised by high temperature and pressure with both steam and saline water, and drift under high temperature and pressure, with very costly unplanned outages. So radiant cannot be specified generically — it calls for sizing source strength against wall thickness, density and licensing requirements.
Solution
The Ainstru engineering team worked through the level range: level solution matched to the actual tank and silo geometry. The configuration involves sizing source strength against wall thickness, density and licensing requirements, with these requirements in view: compliance with power-industry codes and unit availability targets.
Results
Since start-up the system has run steadily; the practical result is measurable under high temperature, pressure and corrosion without intruding into the vessel.
