Level Sensors for Industrial Tanks & Silos
Compare contact and non-contact level technologies for tanks and silos. Confirm the selected model's current range, accuracy, output, materials, test documents, and warranty in the controlled datasheet and quotation.
Use process conditions and installation constraints to narrow capacitive, radar, ultrasonic, or connected level sensing. Published card values are selection inputs, not a final project specification; engineering must confirm the model, configuration, document scope, and commercial terms for the RFQ.

Level Sensors Selection Guide
Use these checks before sending an RFQ. They help our engineers confirm the right model, output, material, and certification for your project.
Match technology to media
Use 80GHz radar for vapor, dust, foam, and tall silos; ultrasonic for clean water tanks; capacitive probes for oil, chemicals, and compact vessels.
Confirm tank geometry
Send tank height, nozzle size, mounting location, internal structures, and dead-zone constraints so the beam angle and range are correct.
Specify output and approval
Confirm the required signal or protocol and list any market or hazardous-area documentation. Verify the exact certificate holder, model scope, marking, and validity before ordering.
