Solide SLDL3351 Series BarScan Hydrostatic Level Transmitter – Accurately Solving Industrial Level Measurement Pain Points and Empowering Efficient Production
May 29, 2026| The Solide SLDL3351 Series BarScan Hydrostatic Level Transmitter launched by Solidat, relying on high performance sensing elements, complete compensation mechanisms and a full certification system, precisely resolves four core pain points in industrial liquid level measurement, providing stable and reliable level measurement solutions for various industries.
Pain Point 1: Low Measurement Accuracy and Large Deviations Affecting Production Decisions and Process Control
Industries including water treatment, food, pharmaceuticals and chemicals impose extremely high requirements on liquid level measurement accuracy. Traditional level transmitters are prone to large measurement deviations caused by temperature drift, poor linearity, density variation and lack of atmospheric pressure compensation. In reservoirs, water supply tanks and chemical storage tank monitoring, even small deviations can lead to inaccurate level control, overflow risks, unbalanced feeding, and even substandard products and material waste.
Case Evidence: A municipal water plant previously used conventional hydrostatic level transmitters with long term measurement deviations of ±0.5%, resulting in unstable pump control and frequent level overshoot. After switching to the SLDL3351, with its standard high accuracy of ±0.2% (optional ±0.1%) and automatic density compensation, measurement stability was greatly improved. Level control became precise and consistent, pump operation was optimized, and annual water waste and energy consumption losses were significantly reduced.
The Solide SLDL3351 Series adopts imported isolated diffused silicon sensing elements or ceramic capacitive pressure sensors, which convert static pressure into electrical signals. After precise temperature compensation and linear correction, it outputs a standard 4~20mA + HART signal. The product features an automatic density compensation function, coupled with a built in atmospheric pressure compensation system, which greatly improves measurement accuracy and long term stability, providing reliable data support for enterprises to precisely control processes, optimize inventory management and avoid economic losses.
Pain Point 2: Poor Overload and Corrosion Resistance Leading to High Failure Rates in Harsh Environments
Industrial sites often involve harsh conditions such as high temperature, high humidity, strong corrosion, dust and hydraulic shock. Traditional level transmitters suffer from easy corrosion of the housing, overload damage to the diaphragm and seal failure, leading to frequent equipment downtime. This not only increases maintenance costs but also seriously affects production continuity. Salt spray and corrosive media in coastal plants, sewage treatment and acid alkali storage tanks further accelerate equipment failure.
Case Evidence: A chemical enterprise handling acidic and slightly abrasive media experienced transmitter failures every 2–3 months with previous devices. After installing the SLDL3351, with its strong anti overload and anti corrosion capabilities and fully sealed structure, the equipment operated continuously and stably for more than 12 months without performance degradation. Maintenance workload dropped sharply and production stability improved significantly.
The SLDL3351 features strong resistance to overload and medium corrosion, and adopts a ceramic measuring unit with high accuracy and long term stability. It has a built in fully sealed electronic module and an atmospheric pressure compensation system, delivering excellent environmental adaptability. The housing and sensing components are corrosion resistant and durable, enabling long term reliable operation in humid, corrosive and fluctuating pressure conditions, significantly reducing failure rates and downtime risks.
Pain Point 3: Complex Installation and Maintenance, Single Function, High Labor and Time Costs
Traditional level transmitters feature cumbersome installation, non standard interfaces and difficult debugging, requiring time consuming work by professional personnel. With single functions, level and temperature must be measured separately, increasing wiring, instrument quantity and potential failure points. Daily maintenance and fault diagnosis are difficult and time consuming, greatly raising labor and time costs for enterprises.
Case Evidence: A water treatment enterprise previously had to install separate level and temperature transmitters, doubling installation and commissioning time. By adopting the SLDL3351 with an optional integrated Pt100 temperature sensor, one device completed both level and temperature measurement. Installation and commissioning time per measuring point was reduced by approximately 50%, the control system was simplified, and maintenance workload was significantly lowered.
The SLDL3351 Series is designed for ease of use and maintenance, supporting standard 4…20mA + HART output with strong compatibility. An optional integrated Pt100 temperature sensor enables simultaneous level and temperature measurement, reducing hardware and installation costs. The rugged and reliable structure minimizes routine maintenance needs, effectively shortening installation, commissioning and troubleshooting time, and reducing comprehensive operation and maintenance costs.
Pain Point 4: Lack of Qualifications and Certifications Unable to Meet Compliance Requirements for Drinking Water, Explosion Protection and Marine Applications
Key scenarios such as drinking water systems, hazardous explosive areas and marine applications impose mandatory certification requirements on instruments. Devices without relevant certifications cannot be deployed, leading to delayed project acceptance and increased compliance risks.
Case Evidence: A drinking water project and a marine application project required instruments with corresponding certifications. With its complete certification system, the SLDL3351 could be directly put into use without additional testing, accelerating project approval and ensuring full compliance throughout the process.
The SLDL3351 Series holds a full set of industry certifications:
Drinking Water Certifications: KTW, NSF, ACS
Explosion proof Certifications: ATEX, FM, CSA
Marine Certifications: GL, ABS
It also provides a full range of supporting accessories to offer users a comprehensive measurement solution, meeting stringent compliance requirements for high end scenarios such as drinking water, hazardous chemicals, marine and municipal applications.
Conclusion
With six core advantages: high measurement accuracy, strong corrosion and overload resistance, high environmental adaptability, easy installation and maintenance, multi function integration and full qualification certification, the Solide SLDL3351 Series BarScan Hydrostatic Level Transmitter successfully resolves many pain points in the field of industrial liquid level measurement. The product has been widely used in water treatment, petrochemical, electric power, metallurgy, food, municipal, marine and other industries, and has won wide recognition from users for its stable and reliable performance and high quality services.
In the future, Solide will continue to uphold the concept of innovation, continuously improve the technical performance of the SLDL3351 Series, provide higher quality and more efficient liquid level measurement solutions for more industries, and help enterprises achieve safe, stable and efficient high quality development.
