What is the accuracy of the ultrasonic level sensor?

The standard accuracy is plus or minus 0.5% FS or plus or minus 5 mm under standard test conditions. OEM accuracy options may reach plus or minus 1 mm, plus or minus 3 mm or plus or minus 0.25% FS depending on the measuring range.

What is the protection rating?

The standard protection class is IP65. IP66, IP67 and IP68 are available for selected OEM configurations.

Where can the PL320 be used?

PL320 can be used for depth wells, industrial tanks, tanker oil level detection, water treatment, hydraulic monitoring and high-pool level measurement. The actual application should be confirmed according to the medium, tank structure, range and installation environment.

Key features

PL320 measures liquid level without direct contact, helping reduce sensor contamination and maintenance requirements in suitable tank applications.

Available measuring ranges extend from up to 5 m to up to 15 m, depending on the selected sensor power and configuration.

The standard model provides a 3-wire 4-20mA output for integration with PLC, DCS and industrial monitoring systems.

Optional configurations include RS485, 0-20mA, 0-5V, 1-5V, 0-10V, 1-10V and combined 4-20mA plus RS485 outputs.

The pictured PL320 system works with the ATTY01 Wi-Fi and BLE IoT Gateway for wireless transmission, Tuya IoT platform access and remote level monitoring.

The sensor supports screw-type or clamp installation, with an M68 x 2.0 mm screw size and quick-connect terminal wiring.

The standard protection class is IP65, while IP66, IP67 and IP68 options are available for selected OEM configurations.

Suitable for depth wells, industrial tanks, tanker oil level detection, water treatment, hydraulic monitoring and high-pool level measurement.

AI-Powered supplier vetting

SummaryThe supplier operates in automatic control systems, intelligent instruments, electronic measuring instruments, electromechanical equipment, communication equipment, and related imports and exports. It reports vertically integrated engineering, manufacturing, sales, marketing, and customer service within one facility, with critical manufacturing, assembly, and testing steps controlled internally. The supplier holds ISO9001:2015, RoHS, and CE certifications. It offers broad customization, including designs and samples, but reports no new products in the past year, no ODM service, and no available SDK. Export experience is stated as 10 years, while overseas agents, branches, warehouses, showrooms, and trade-show participation are absent. Lead times are within 15 working days in both peak and off-season, supported by written supplier-management procedures. Financial records are indicated for 2021–2023, but no financial figures or performance results are provided. No specific customer cases or named-brand OEM...

Supplier typeThe supplier is a manufacturer and seller of automatic control systems, intelligent instruments, electronic measuring instruments, electronic components, electromechanical equipment, and communication equipment. Its stated vertical integration and internal control of manufacturing, assembly, and testing support classification as an integrated industrial equipment/instrument manufacturer rather than only a trading company.

CertificationsThe supplier reports an ISO9001:2015 management-system certificate and RoHS and CE product compliance certifications. These explicitly demonstrate documented quality management and stated product compliance coverage.

R&D capabilityThe supplier states that it had no new products during the past year, does not provide ODM services, and has no available SDK. These are explicit limitations in recent product innovation and development support.

Production capacityThe supplier reports vertical integration and internal control of critical manufacturing, assembly, and testing steps, with a stated lead time within 15 working days in both peak and off-season. It also has written supplier-management procedures and records, but reports no in-stock capacity; overall production capability is supported, while inventory capacity is limited.

Customization capabilityThe supplier explicitly offers flexible, minor, and full customization, including customization from customer designs and samples. This indicates broad customization execution capability, although it does not include ODM service.

Product Q&A

Q:How does the PL320 measure liquid level?

PL320 uses non-contact ultrasonic measurement. It measures the distance between the ultrasonic sensor surface and the target liquid surface in standard distance mode.

Q:What is the maximum measuring range?

The maximum range depends on the selected sensor configuration and can be up to 5 m, 7 m, 10 m, 12 m or 15 m. The actual range also depends on the smoothness and conditions of the liquid surface.

Q:What is the standard output signal?

The standard model provides a 3-wire 4-20mA output. Other signal configurations are available for OEM orders.

Q:Does the sensor support RS485?

Yes. RS485 is available as an OEM configuration. The default communication settings shown in the document are MCU protocol, address 01 and 9600 bps.

Q:Does PL320 have built-in Wi-Fi, BLE or Tuya connectivity?

The PL320 sensor itself is not described as having built-in Wi-Fi, BLE or Tuya functions. The pictured solution uses an ATTY01 Wi-Fi and BLE IoT Gateway to transmit data to the Tuya IoT platform for remote monitoring.
