Application area
The VEGAWAVE 63 is a level switch for universal use in powders andfine-grained bulk solids. The VEGAWAVE 63 detects reliably and robustthe min. or max. level. The tuning fork is ideal for use either in adhesiveand abrasive products as well as in bulk solids with very low density.The position of the switching point is determined via the tube extension.
Your benefit
- Minimum time and cost expenditure thanks to simple setup without
- medium
- Reliable function due to product-independent switching point
- Low maintenance costs thanks to robust design
Function
With the VEGAWAVE 63 series, the tuning fork is used as sensor element. If the medium covers the tuning fork, the amplitude is damped.The electronics detects this damping and converts it into a switchingcommand.
Case Studies
Municipal Wastewater Treatment · tuning fork — 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 vibrating-fork point level detection and high/low alarms.
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 fork length and surface finish by density and stickiness.
What We Did
We took a level range approach — level solution matched to the actual tank and silo geometry. Delivery was built around choosing fork length and surface finish by density and stickiness, 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 calibration needed, with dependable switching, with routine maintenance falling noticeably.
Food & Beverage · tuning fork — Application Case
Application Context
dosing, pasteurising, filling and CIP stages is a typical Food & Beverage duty. The project started from tuning fork, focusing on vibrating-fork point level detection and high/low alarms.
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 tuning fork specification must therefore cover choosing fork length and surface finish by density and stickiness.
Delivery Approach
Delivery was handled as the level range — level solution matched to the actual tank and silo geometry. Execution centred on choosing fork length and surface finish by density and stickiness, together with food-safety and hygienic design per 3-A / EHEDG.
Field Results
Operation shows the benefit clearly — no calibration needed, with dependable switching, with confidence in this measuring point improving markedly.
Chemical & Pharmaceutical · tuning fork — Application Case
Customer Profile
The typical setting in Chemical & Pharmaceutical is reactors, metering vessels and finished-product tanks. The measuring point is tuning fork; the focus is vibrating-fork point level detection and high/low alarms.
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 fork length and surface finish by density and stickiness.
Implementation
The scope ran through the level range: level solution matched to the actual tank and silo geometry. Technically it hinges on choosing fork length and surface finish by density and stickiness, and on these requirements: Ex certification and GMP traceability of records.
Customer Benefit
In practice this means no calibration needed, with dependable switching, which cut the workload on the site maintenance team.
Power & Energy · tuning fork — Application Case
Project Background
The project covers boiler feedwater, turbine condensate and FGD/DeNOx systems. The work centres on tuning fork and the core task is vibrating-fork point level detection and high/low alarms.
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 tuning fork cannot be specified generically — it calls for choosing fork length and surface finish by density and stickiness.
Solution
The Ainstru engineering team worked through the level range: level solution matched to the actual tank and silo geometry. The configuration involves choosing fork length and surface finish by density and stickiness, 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 calibration needed, with dependable switching.
