Municipal Wastewater Treatment

Municipal Wastewater Treatment · Vortex flowmeter — Application Case

Project Background

The project covers the inlet, biological and outlet stages of a municipal plant. The work centres on Vortex flowmeter and the core task is flow of steam, gases and low-viscosity liquids.

Operating Challenges

The medium and duty are characterised by high solids and corrosive fractions, with large diurnal flow swings, and effluent parameters drift and probes foul with sludge and biofilm. So Vortex flowmeter cannot be specified generically — it calls for sizing bore and bluff body by minimum flow, vibration and temperature.

Solution

The Ainstru engineering team worked through the flow range: flow solution matched to line size, medium and range. The configuration involves sizing bore and bluff body by minimum flow, vibration and temperature, with these requirements in view: stable compliance with Grade 1A discharge limits and online data reporting.

Results

Since start-up the system has run steadily; the practical result is no moving parts, so steam metering stays stable over years.

Food & Beverage

Food & Beverage · Vortex flowmeter — Application Case

Project Overview

The site is dosing, pasteurising, filling and CIP stages. The customer wanted Vortex flowmeter properly configured on the existing plant, with the aim of flow of steam, gases and low-viscosity liquids.

Technical Challenges

What actually causes trouble is syrups, dairy and beverages that scale easily, under strict hygienic requirements, and frequent cleaning demands instruments that withstand hot CIP/SIP caustic cycles. All of this means the Vortex flowmeter configuration has to involve sizing bore and bluff body by minimum flow, vibration and temperature.

Configuration

Supply and installation were organised through the flow range: flow solution matched to line size, medium and range. On site this meant sizing bore and bluff body by minimum flow, vibration and temperature, checked line by line against: food-safety and hygienic design per 3-A / EHEDG.

Performance

After commissioning the outcome is no moving parts, so steam metering stays stable over years, and the readings are now used for process tuning.

Chemical & Pharmaceutical

Chemical & Pharmaceutical · Vortex flowmeter — Application Case

Site Conditions

This is a Chemical & Pharmaceutical customer whose plant is at reactors, metering vessels and finished-product tanks. The main task was flow of steam, gases and low-viscosity liquids.

The Problem

The difficulty lies in highly corrosive media with solvents and crystallisation, partly in explosive atmospheres; at the same time corrosion plus Ex protection shortens instrument life and makes downtime costly. Specification therefore means sizing bore and bluff body by minimum flow, vibration and temperature.

What We Did

We took a flow range approach — flow solution matched to line size, medium and range. Delivery was built around sizing bore and bluff body by minimum flow, vibration and temperature, with point-by-point checks on: Ex certification and GMP traceability of records.

Operating Outcome

In service the system performs as intended — no moving parts, so steam metering stays stable over years, with routine maintenance falling noticeably.

Power & Energy

Power & Energy · Vortex flowmeter — Application Case

Application Context

boiler feedwater, turbine condensate and FGD/DeNOx systems is a typical Power & Energy duty. The project started from Vortex flowmeter, focusing on flow of steam, gases and low-viscosity liquids.

Process Constraints

drift under high temperature and pressure, with very costly unplanned outages, and high temperature and pressure with both steam and saline water only amplify it. The Vortex flowmeter specification must therefore cover sizing bore and bluff body by minimum flow, vibration and temperature.

Delivery Approach

Delivery was handled as the flow range — flow solution matched to line size, medium and range. Execution centred on sizing bore and bluff body by minimum flow, vibration and temperature, together with compliance with power-industry codes and unit availability targets.

Field Results

Operation shows the benefit clearly — no moving parts, so steam metering stays stable over years, with confidence in this measuring point improving markedly.
