When to Use Hygienic Vibronic Point-Level Switches
Hygienic vibronic level switches are used when a process needs a dependable point-level signal rather than continuous level measurement. This guide helps engineering, maintenance and purchasing teams prepare an accurate technical check for a hygienic liquid application, a replacement request or a quotation. It is not a substitute for the latest manufacturer datasheet, order code or site engineering review.
Define the Measurement Task First
Start with the measurement task. Confirm whether the instrument is needed for high-level alarm, low-level alarm, dry-run protection, pump control or another point-level function. Also confirm whether the switch is installed in a process tank, storage tank or pipeline. A model name alone is not enough to establish a like-for-like replacement.
Information to Confirm Before Selecting or Replacing
Provide the complete order code or a clear nameplate photo, the installed connection and insertion length, the process medium, operating temperature and pressure, and the required output or protocol. For hygienic service, also identify the product-contact material, surface requirement, cleaning method, CIP/SIP conditions and any site-specific approval or certificate requirement. Quantity, destination country and required delivery date help complete a quotation request.
Where the Liquiphant FTL63 Fits
Liquiphant FTL63 is a hygienic vibronic point-level switch for liquids. The manufacturer describes its use in process and storage tanks and pipelines, particularly where hygienic design and liquid point-level detection are important. Suitability must be checked against the exact configuration and current official documentation. Do not assume that a different Liquiphant model, a float switch, a capacitive sensor or an optical sensor is an automatic replacement without comparing the process connection, electrical output, approvals and application conditions.
A Practical Replacement Checklist
Identify the existing device from its full order code or nameplate. Compare the mechanical connection, wetted materials, insertion geometry, electrical supply and signal type. Confirm the process duty, including medium behavior, temperature, pressure, foam, deposits and cleaning cycle. Finally, verify certificate and documentation requirements for the destination and application before releasing the order.
Get a Model-Specific Technical Check
Send the FTL63 model code or nameplate with application details through the Technical Support page, or request a quotation.
