Municipal Wastewater Treatment · Electromagnetic flow meter — 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 volumetric flow of conductive liquids.
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 choosing liner and electrode pairing by conductivity, solids and abrasion.
What We Did
We took a flow range approach — flow solution matched to line size, medium and range. Delivery was built around choosing liner and electrode pairing by conductivity, solids and abrasion, 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 — no obstruction, so pressure loss is minimal and upkeep low, with routine maintenance falling noticeably.
Food & Beverage · Electromagnetic flow meter — Application Case
Application Context
dosing, pasteurising, filling and CIP stages is a typical Food & Beverage duty. The project started from Electromagnetic flow meter, focusing on volumetric flow of conductive liquids.
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 Electromagnetic flow meter specification must therefore cover choosing liner and electrode pairing by conductivity, solids and abrasion.
Delivery Approach
Delivery was handled as the flow range — flow solution matched to line size, medium and range. Execution centred on choosing liner and electrode pairing by conductivity, solids and abrasion, together with food-safety and hygienic design per 3-A / EHEDG.
Field Results
Operation shows the benefit clearly — no obstruction, so pressure loss is minimal and upkeep low, with confidence in this measuring point improving markedly.
Chemical & Pharmaceutical · Electromagnetic flow meter — Application Case
Customer Profile
The typical setting in Chemical & Pharmaceutical is reactors, metering vessels and finished-product tanks. The measuring point is Electromagnetic flow meter; the focus is volumetric flow of conductive liquids.
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 choosing liner and electrode pairing by conductivity, solids and abrasion.
Implementation
The scope ran through the flow range: flow solution matched to line size, medium and range. Technically it hinges on choosing liner and electrode pairing by conductivity, solids and abrasion, and on these requirements: Ex certification and GMP traceability of records.
Customer Benefit
In practice this means no obstruction, so pressure loss is minimal and upkeep low, which cut the workload on the site maintenance team.
Power & Energy · Electromagnetic flow meter — Application Case
Project Background
The project covers boiler feedwater, turbine condensate and FGD/DeNOx systems. The work centres on Electromagnetic flow meter and the core task is volumetric flow of conductive liquids.
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 Electromagnetic flow meter cannot be specified generically — it calls for choosing liner and electrode pairing by conductivity, solids and abrasion.
Solution
The Ainstru engineering team worked through the flow range: flow solution matched to line size, medium and range. The configuration involves choosing liner and electrode pairing by conductivity, solids and abrasion, 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 no obstruction, so pressure loss is minimal and upkeep low.
