How to use radar level transmitters for batch processing in tanks?

Set 'high' and 'low' level alarms via the transmitter's software. When the liquid reaches the high level, the alarm triggers to stop filling; when it reaches the low level, the alarm triggers to start refilling. Most models support analog (4-20mA) or digital (Modbus) output for integration with PLCs.

AI-Powered supplier vetting

SummaryThe supplier is identified as a trading company engaged in sensor, transmitter, and related instrument research, manufacturing, sales, and service. It reports ISO 9001-related certification, TS 16949 and ISO 20000 certifications, CE capability, ERP integration, three production lines, and documented procedures for supplier-service assessment, corrective actions, and complaint handling. It offers 3D design, ODM, and multiple customization models, but reports no new products during the past year, no SDK, and no OEM service for popular brands. Overseas service infrastructure is limited: no overseas warehouse, showroom, agent, or branch, and the stated overseas-service country count is zero. Financial records are referenced for recent years, but the provided slices do not disclose sufficient non-financial evidence to assess financial credibility. No customer cases are provided.

Supplier typeThe supplier is explicitly classified as a trading company. Its company description states that it conducts research, development, manufacturing, sales, and service for sensors, transmitters, and related instruments.

CertificationsThe supplier reports TS 16949, ISO 9001, and ISO 20000 certifications, along with an ISO 9001:2015 certificate and CE certification capability. These stated certifications provide explicit evidence of formal quality or management-system credentials.

After-Sales capabilityThe supplier reports documented and followed procedures for corrective and preventive actions and customer complaints. However, it has no overseas warehouse, showroom, agent, or branch, and the stated overseas-service country count is zero, indicating documented service processes but limited overseas service infrastructure.

Production capacityThe company describes itself as involved in manufacturing sensors and related instruments and reports operating three production lines. It also provides a stated water-level-sensor output figure, but the overall production scale and broader capacity are not sufficiently detailed for a complete capability assessment.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, flexible customization, and ODM services. This is direct evidence of broad product customization capability.

Product Q&A

Q:How does a radar level transmitter work for liquid level measurement?

It transmits microwave signals (typically 6GHz, 24GHz, or 80GHz) from an antenna towards the liquid surface. The signals reflect off the surface, and the transmitter analyzes the frequency shift (for FMCW radar) or time delay (for pulsed radar) of the reflected signals to compute the level accurately.

Q:In which scenarios is a radar level transmitter more suitable than an ultrasonic sensor?

High-temperature/pressure tanks, volatile/flammable liquid storage, dusty environments (e.g., cement silos), low dielectric constant liquids, and long measurement ranges (over 10m).

Q:Can radar level transmitters be installed outdoors?

Yes, if they have an IP67/IP68 protection rating. Use a sunshade or heater (for cold climates) to prevent damage from extreme temperatures, rain, or snow. Ensure the antenna is not blocked by debris.

Q:What is the response time of radar level transmitters?

Typically 0.1 to 1 second. Pulsed radar has a faster response time than FMCW radar, making it suitable for applications with rapidly changing liquid levels (e.g., filling/draining tanks).

Q:Do radar level transmitters work for liquid-solid mixtures (e.g., slurry with particles)?

Yes, if the solid particles are small (<1mm) and the liquid has a stable surface. For thick slurries or high-solid-content mixtures, choose radar with a rugged antenna (e.g., stainless steel) to resist clogging.
