The Liquiphant FTL33 liquid point level switch is designed specifically for the food and beverage industry with high hygienic requirements. The Liquiphant is especially suitable for overflow protection or pump dry-run protection in storage tanks, mixing tanks and pipes.
Compact:
- The smallest vibronic sensor on the market
Safe:
- Continuous self-monitoring
- Reliable switching unaffected by the properties of the medium
Simple:
- No calibration or adjustment required
- Plug and play

Benefits:

Designed for hygienic applications, especially in the food industry - with hygienic process connections and certifications
Withstands CIP and SIP cleaning - highest protection rating IP69k
Designed to meet the highest quality and environmental sustainability requirements; the self-monitoring Liquiphant provides safe switching even in the event of a power failure.
Provides precise switch points unaffected by changes in medium properties
Plug-and-play point level switch requiring no adjustment under changing media conditions. The measurement is unaffected by conductivity, buildup, turbulence, flow or bubbles
No calibration, specific knowledge or tools required (e.g. software)
Rugged stainless steel (316L) with the highest durability - no mechanical moving parts, maintenance-free

Application areas:
The FTL33 is a compact point level switch for hygienic applications, suitable for liquid measurement in the food industry and in the life sciences industry.

Municipal Wastewater Treatment

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

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

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

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.
