SW800 Tank Level Sensors

SW800 tank level sensors are precision instruments with stainless steel housing and vented cable, offering +/-0.1% accuracy for reliable water monitoring.

Our range of water tank level sensors are highly engineered, precision instruments and form the core sensing element of the system. The engineering investment made in this part of the system offers our customers the reward of second-to-none accuracy and reliability. The research and development team at Smart Water have spent years perfecting this sensor and can now offer the market the ultimate solution for water tank monitoring.

High-performance specifications

The internal electronics in the sensor are potted in resin that ensures no moisture penetration into this delicate instrument. The electronics are linked to an ultra-accurate piezoresistive sensing element, and then wrapped in the highest quality SS316 stainless steel housing. Ruggedised polyethylene vented cable is utilised, offering both UV, weather and crush resistance. The vented cable is a critical part of the design, ensuring changing weather conditions do not affect the accuracy of the tank level measurements. With all of this technology combined, we achieve accuracy of +/-0.1% on an ongoing and reliable basis.

Your needs and requirements are covered

Currently, there are four different water tank level sensors to choose from at lengths of 4M and 10M. There are options for both standard pressure (0.5bar/500kPa) and high-pressure (1.0bar/1000kPa) models. This gives the flexibility of measuring deeper tanks, or even different types of fluids with different specific gravities (SG). The Smart Water range of tank level senders are compatible with both the legacy SW800 series and the new SW900 series systems.

Support for Legacy SW800 Systems

SW800 sensors remain fully compatible with legacy SW800 systems, allowing users to maintain, replace, or expand existing installations without upgrading to the SW900. This ensures continued performance and monitoring accuracy for customers with installed SW800 systems.

Available SW800 Sensor Models

Smart Water offers a range of SW800 sensor models to suit different tank types and depths. There are standard and high-pressure versions available in 4M and 10M lengths. These options provide flexibility for shallow or deep tanks and for fluids with varying specific gravities.

Standard & High-Pressure Options

Standard sensors measure up to 0.5 bar (500kPa), while high-pressure sensors measure up to 1.0 bar (1000kPa). This allows users to select the right sensor for tank size, depth, and fluid density, ensuring accurate readings in any situation.

4M and 10M Sensor Lengths

Available in 4M and 10M lengths, SW800 sensors can accommodate tanks of varying depths. This flexibility makes them ideal for residential, rural, and commercial water systems.

High-Performance Sensor Specifications

SW800 sensors are engineered for high accuracy and durability. Internal electronics are potted in resin to prevent moisture ingress, while ultra-accurate piezoresistive sensing elements ensure precise measurement. Accuracy is maintained at ±0.1%, even in changing environmental conditions.

Stainless Steel Housing & Ruggedised Cable

All sensors are enclosed in SS316 stainless steel housings for long-term protection. Vented polyethylene cables provide UV resistance, weather protection, and crush resistance, safeguarding sensor performance over years of use.

Accuracy and Reliability in All Conditions

The vented cable design compensates for temperature and weather variations, ensuring that readings remain consistent. Combined with high-quality materials and robust construction, SW800 sensors provide reliable, continuous monitoring for all types of water tanks.
