What can you suggest for level measurement in sewage wastewater up to 5 metres deep, which has a diameter no more than 30mm, a ceramic cell membrane, submersible with 15 metre length of cable and 2 wire 4-20mA signal?
The LMK307 submersible level sensor is designed for accurate and reliable level measurement in sewage wastewater applications. With its robust construction and specialized features, it excels in challenging environments commonly found in wastewater treatment facilities.
One of the key features of the LMK307 is its flush ceramic sensing diaphragm. This design ensures minimal obstruction to the flow of sewage, reducing the risk of clogging or fouling that can affect the accuracy of measurements. The ceramic material is highly resistant to corrosion and abrasion, ensuring long-term stability and performance even when exposed to harsh chemicals and suspended solids typically present in sewage.
The sensor’s submersible design allows for direct installation into the wastewater, providing continuous level monitoring. Its compact 30mm diameter makes it suitable for integration into various tank sizes and configurations, including narrow or restricted spaces. The 15-meter long cable offers flexibility in installation and ensures that the sensor can be positioned at the optimal depth for accurate readings.
The LMK307 utilizes a 2-wire 4-20mA output signal, a widely accepted industry standard for transmitting level data. This signal provides a reliable and robust means of communication, minimizing the effects of electrical noise and interference often encountered in industrial settings. The sensor’s 0.5% FS accuracy ensures precise level measurements, enabling effective process control and management.
Furthermore, the LMK307 is ATEX approved, making it suitable for use in potentially explosive atmospheres. This certification is crucial for ensuring safety in wastewater treatment plants where flammable gases or vapors may be present. The sensor’s stainless steel 316L housing and FKM seals provide additional protection against corrosion and chemical attack, further enhancing its durability and longevity.
The LMK307 is particularly well-suited for applications such as:
- Monitoring sewage levels in lift stations and pump sumps
- Controlling the inflow and outflow of wastewater treatment tanks
- Measuring the level of sewage in storage tanks and reservoirs
- Detecting blockages or overflows in sewage pipelines
Its ability to withstand harsh conditions and provide accurate and reliable measurements makes it an invaluable tool for maintaining efficient and safe operation of wastewater treatment facilities.
