Endress+Hauser FQG60 Source container

Source container FQG60

Endress+Hauser FQG60

The FQG60 source container is designed to hold the radioactive source during radiometric point level detection, continuous level and density measurement. The radiation is emitted almost unattenuated in one direction only, and is damped in all other directions. This guarantees highest safety for the personnel and a reliable measurement.

Municipal Wastewater Treatment

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

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

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

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.
