Case Studies
Municipal Wastewater Treatment · ultrasound — Application Case
Application Context
the inlet, biological and outlet stages of a municipal plant is a typical Municipal Wastewater Treatment duty. The project started from ultrasound , focusing on ultrasonic liquid level measurement or interface detection.
Process Constraints
effluent parameters drift and probes foul with sludge and biofilm, and high solids and corrosive fractions, with large diurnal flow swings only amplify it. The ultrasound specification must therefore cover sizing range against dead zone, mounting height and medium temperature.
Delivery Approach
Delivery was handled as the level range — level solution matched to the actual tank and silo geometry. Execution centred on sizing range against dead zone, mounting height and medium temperature, together with stable compliance with Grade 1A discharge limits and online data reporting.
Field Results
Operation shows the benefit clearly — retrofit without touching the tank, with short installation time, with confidence in this measuring point improving markedly.
Food & Beverage · ultrasound — Application Case
Customer Profile
The typical setting in Food & Beverage is dosing, pasteurising, filling and CIP stages. The measuring point is ultrasound ; the focus is ultrasonic liquid level measurement or interface detection.
Key Difficulties
Conditions are syrups, dairy and beverages that scale easily, under strict hygienic requirements and, on top of that, frequent cleaning demands instruments that withstand hot CIP/SIP caustic cycles, which a standard configuration cannot handle for long. The design therefore starts with sizing range against dead zone, mounting height and medium temperature.
Implementation
The scope ran through the level range: level solution matched to the actual tank and silo geometry. Technically it hinges on sizing range against dead zone, mounting height and medium temperature, and on these requirements: food-safety and hygienic design per 3-A / EHEDG.
Customer Benefit
In practice this means retrofit without touching the tank, with short installation time, which cut the workload on the site maintenance team.
Chemical & Pharmaceutical · ultrasound — Application Case
Project Background
The project covers reactors, metering vessels and finished-product tanks. The work centres on ultrasound and the core task is ultrasonic liquid level measurement or interface detection.
Operating Challenges
The medium and duty are characterised by highly corrosive media with solvents and crystallisation, partly in explosive atmospheres, and corrosion plus Ex protection shortens instrument life and makes downtime costly. So ultrasound cannot be specified generically — it calls for sizing range against dead zone, mounting height and medium temperature.
Solution
The Ainstru engineering team worked through the level range: level solution matched to the actual tank and silo geometry. The configuration involves sizing range against dead zone, mounting height and medium temperature, with these requirements in view: Ex certification and GMP traceability of records.
Results
Since start-up the system has run steadily; the practical result is retrofit without touching the tank, with short installation time.
Power & Energy · ultrasound — Application Case
Project Overview
The site is boiler feedwater, turbine condensate and FGD/DeNOx systems. The customer wanted ultrasound properly configured on the existing plant, with the aim of ultrasonic liquid level measurement or interface detection.
Technical Challenges
What actually causes trouble is high temperature and pressure with both steam and saline water, and drift under high temperature and pressure, with very costly unplanned outages. All of this means the ultrasound configuration has to involve sizing range against dead zone, mounting height and medium temperature.
Configuration
Supply and installation were organised through the level range: level solution matched to the actual tank and silo geometry. On site this meant sizing range against dead zone, mounting height and medium temperature, checked line by line against: compliance with power-industry codes and unit availability targets.
Performance
After commissioning the outcome is retrofit without touching the tank, with short installation time, and the readings are now used for process tuning.
