Votronic Tank Level Sensor FL 5530

DESCRIPTION

Precise Capacitive Tank Level Monitoring for Mobile and Off-Grid Water Systems

Reliable Measurement Without Pressure-Related Errors

The Votronic Tank Level Sensor FL 5530 uses advanced capacitive measuring technology to deliver accurate, real-time fluid level data for fresh water, waste water, and grey water tanks. Unlike traditional float or pressure-based sensors, this system operates independently of tank pressure, eliminating false readings caused by overpressure, pressure filling, or sloshing during transit. This makes it an ideal choice for caravan water tanks, motorhome grey water systems, marine fresh water monitoring, and other mobile applications where consistent accuracy is critical.

Designed for both short-term and continuous operation, the sensor provides a linear 0–2.2 V signal output proportional to the tank level (0–100%), ensuring seamless integration with compatible Votronic display units and control panels.

Flexible Installation for Metal and Plastic Tanks

The FL 5530 supports top-mount or side-wall installation, with an adjustable probe length that can be cut to fit tank heights from 30 cm to 100 cm. The included stainless steel conductor and flexible cord probe allow precise positioning, while the watertight screwed cable gland ensures a secure, moisture-resistant seal. Suitable for aluminium, steel, stainless steel, and plastic tanks (up to 8 mm wall thickness for plastic), this sensor adapts to a wide range of tank materials and configurations.

A cleaning opening is required for installation, and the sensor module’s compact, sealed design (IP 67) withstands frost, moisture, and underfloor mounting conditions—making it suitable for problematic locations such as exposed chassis-mounted tanks.

Key Features at a Glance

  • Capacitive sensing eliminates pressure-induced measurement errors
  • Adjustable probe length suits tank heights from 30 cm to 100 cm
  • IP 67 sealed electronics resist frost, moisture, and underfloor conditions

Built for Demanding Environments

The sensor’s fully potted electronics and corrosion-resistant materials ensure long-term reliability in coastal, humid, or high-vibration settings. Compliance with EN55014-1, EN61000-6-1, EN61000-4-2, EN61000-4-3, EN61000-4-4, EN62368-1, and EN50498 standards confirms its electromagnetic compatibility and safety, while RoHS compliance supports environmentally responsible manufacturing.

With a low current draw of just 4–7 mA, the FL 5530 minimises battery drain in off-grid setups, preserving power for essential systems. Its 3-core screw terminal connection simplifies wiring to compatible displays, and the included fastening screws and tank wall bushing streamline installation.

WARRANTY

VOTRONIC Warranty Policy

This warranty policy applies to VOTRONIC products supplied by us in Australia. VOTRONIC products supplied by us are covered by a 60 month warranty against defects in materials or manufacture, subject to the product being used, installed and operated correctly and in accordance with the manufacturer's instructions.

This warranty applies to the original end-user purchaser of the product, as evidenced by a valid proof of purchase, and is not transferable unless otherwise agreed in writing.

The benefits given by this warranty are in addition to other rights and remedies available under law.

Warranty Coverage and Periods

This warranty covers VOTRONIC products supplied by us, including charging devices, inverters, converters, monitoring devices, display devices and related accessories. The warranty periods for each product range are set out below.

Installer Responsibilities and System Design

VOTRONIC products are commonly installed, connected, configured or integrated into a broader electrical system, vehicle, vessel, caravan, motorhome or other operating environment. Once installed, the product may form only one component of a larger system.

We do not provide installation services unless expressly stated in writing, and we do not supervise or control installation practices carried out by dealers, installers, contractors or end-users. The installer, system designer, integrator, dealer or end-user is responsible for ensuring that the product is suitable for the intended application and is installed correctly.

Issues or damage arising from incorrect installation, poor system design, incorrect configuration, incompatible equipment, inadequate protection, unsuitable mounting, unsuitable environmental conditions or failure to follow the manufacturer's instructions are not product defects and are not covered by this warranty.

Appropriate Installation

All VOTRONIC products must be installed in accordance with the product manual, the manufacturer's installation instructions, applicable Australian Standards, relevant electrical, automotive, marine or industry standards, and recognised industry best practice.

The installer must ensure that the product is used in an appropriate environment and within its specified ratings. Improper, unsafe, unlicensed, sub-standard or non-compliant installation may void or limit warranty coverage.
