SISCO radar level meter offers dependable non-contact level measurement for chemical storage tanks, reactors, and industrial process vessels handling corrosive liquids. Designed with an IP65-rated housing, DC24V/AC220V power supply, flange installation, and 4–20 mA output with HART and RS485 communication, it delivers reliable operation under process pressures up to 2.0 MPa.
Accurate & Stable Measurement Performance
- 3° narrow beam design: The ultra-narrow beam angle concentrates radar energy intensely for stronger penetration. The radar level transmitter boosts echo signals from liquid surfaces and effectively bypasses obstacles inside tanks to eliminate measuring errors.
- High measuring precision: Adopting the electromagnetic wave measurement principle, the transmitter is unaffected by vacuum, high temperature, high pressure, and other harsh conditions, for wide application coverage. Equipped with high-frequency pulse technology, the radar level sensor delivers precise measurements with a tiny blind zone to detect both high and low liquid levels accurately.
Durable Sealed Protection Structure
The whole unit is rated IP65, a high protection class with sealed cable glands. This radar level transmitter provides triple protection against water ingress, dust accumulation and corrosive substances, enabling long-term stable operation in humid, outdoor and corrosive chemical environments.
Applications
This series of radar level transmitters is applicable to a wide range of harsh industrial working conditions. It fits sanitary tanks for clean raw materials and pharmaceutical liquids in the food, beverage, and pharmaceutical industries to measure mildly corrosive liquids under normal pressure stably. Also, the radar level sensor works for chemical storage tanks with strong corrosive media such as acids, alkalis, and salts, as well as tanks containing high-temperature steam and volatile liquids.

Dimension (unit: mm)
Q1: Why choose a radar level transmitter instead of a guided wave radar transmitter?
A1: A non-contact radar level transmitter is often preferred for corrosive liquids because the antenna does not contact the chemical medium, eliminating probe corrosion and reducing maintenance. Guided wave radar is typically selected when extremely low dielectric liquids or interface measurements require direct signal guidance.
Q2: Can radar level transmitters measure liquids with steam or condensation?
A2: Yes. Modern radar technology is specifically designed to reduce interference from steam, condensation, and vapor. This makes radar level transmitters particularly suitable for heated chemical tanks and process vessels where ultrasonic sensors may struggle to provide stable measurements.
Q3: Can a radar level transmitter work under high temperature and pressure?
A3: Yes. Depending on the model, radar level transmitters can operate at process temperatures up to 150°C and process pressures ranging from -0.1 MPa to 2.0 MPa. High-temperature versions are also available for more demanding applications.
Tips: Does the transmitter require regular maintenance?
No. Radar level transmitters require minimal maintenance because they use non-contact radar technology, eliminating direct contact between the sensor and the corrosive liquid. This design reduces wear, prevents chemical corrosion of the sensing element, and ensures long-term measurement stability. To maintain optimal performance, it is recommended to periodically inspect the antenna for buildup, verify that the process connection remains secure, and check the electrical connections during routine system maintenance. Under normal operating conditions, the transmitter can provide reliable, maintenance-free operation for many years.
