Municipal Wastewater Treatment · brackets — Application Case
Customer Profile
The typical setting in Municipal Wastewater Treatment is the inlet, biological and outlet stages of a municipal plant. The measuring point is brackets; the focus is mounting, fixation and position adjustment for instruments.
Key Difficulties
Conditions are high solids and corrosive fractions, with large diurnal flow swings and, on top of that, effluent parameters drift and probes foul with sludge and biofilm, which a standard configuration cannot handle for long. The design therefore starts with checking structural strength by material, corrosion class and load.
Implementation
The scope ran through the system components range: supplying as a full cabinet and signal-chain configuration. Technically it hinges on checking structural strength by material, corrosion class and load, and on these requirements: stable compliance with Grade 1A discharge limits and online data reporting.
Customer Benefit
In practice this means accurate mounting positions that remove measurement bias at the source, which cut the workload on the site maintenance team.
Food & Beverage · brackets — Application Case
Project Background
The project covers dosing, pasteurising, filling and CIP stages. The work centres on brackets and the core task is mounting, fixation and position adjustment for instruments.
Operating Challenges
The medium and duty are characterised by syrups, dairy and beverages that scale easily, under strict hygienic requirements, and frequent cleaning demands instruments that withstand hot CIP/SIP caustic cycles. So brackets cannot be specified generically — it calls for checking structural strength by material, corrosion class and load.
Solution
The Ainstru engineering team worked through the system components range: supplying as a full cabinet and signal-chain configuration. The configuration involves checking structural strength by material, corrosion class and load, with these requirements in view: food-safety and hygienic design per 3-A / EHEDG.
Results
Since start-up the system has run steadily; the practical result is accurate mounting positions that remove measurement bias at the source.
Chemical & Pharmaceutical · brackets — Application Case
Project Overview
The site is reactors, metering vessels and finished-product tanks. The customer wanted brackets properly configured on the existing plant, with the aim of mounting, fixation and position adjustment for instruments.
Technical Challenges
What actually causes trouble is highly corrosive media with solvents and crystallisation, partly in explosive atmospheres, and corrosion plus Ex protection shortens instrument life and makes downtime costly. All of this means the brackets configuration has to involve checking structural strength by material, corrosion class and load.
Configuration
Supply and installation were organised through the system components range: supplying as a full cabinet and signal-chain configuration. On site this meant checking structural strength by material, corrosion class and load, checked line by line against: Ex certification and GMP traceability of records.
Performance
After commissioning the outcome is accurate mounting positions that remove measurement bias at the source, and the readings are now used for process tuning.
Power & Energy · brackets — Application Case
Site Conditions
This is a Power & Energy customer whose plant is at boiler feedwater, turbine condensate and FGD/DeNOx systems. The main task was mounting, fixation and position adjustment for instruments.
The Problem
The difficulty lies in high temperature and pressure with both steam and saline water; at the same time drift under high temperature and pressure, with very costly unplanned outages. Specification therefore means checking structural strength by material, corrosion class and load.
What We Did
We took a system components range approach — supplying as a full cabinet and signal-chain configuration. Delivery was built around checking structural strength by material, corrosion class and load, with point-by-point checks on: compliance with power-industry codes and unit availability targets.
Operating Outcome
In service the system performs as intended — accurate mounting positions that remove measurement bias at the source, with routine maintenance falling noticeably.
