●Narrow Beam and High Sensitivity: 13° narrow beam angle combined with > -57dB high sensitivity ensures accurate capture of transit time differences even in complex flow fields, improving flow measurement accuracy.

●Long-Distance Transmission: Usable distance up to 10m, facilitating long-distance signal connections between central control rooms and field instruments.

4. Typical Applications

●Oil & Gas Pipeline Flow Metering: Used for non-contact ultrasonic flow measurement in high-pressure natural gas, crude oil, and refined product pipelines.

●High-Pressure Industrial Gas Flowmeters: Integrated into precision metering systems for industrial gases such as nitrogen, hydrogen, and compressed air.

●Chemical Process Metering: Suitable for process control and batch metering of high-temperature, corrosive chemical media.

●Liquid Level Detection: Used for level monitoring in high-pressure vessels, reactors, and storage tanks, particularly suitable for viscous or high-temperature liquids.

5. Usage and Warranty Instructions

●Drive Voltage Limitation: Recommended drive voltage ≤1500Vpp to avoid exceeding the piezoelectric element's tolerance limit. It is advisable to use a dedicated ultrasonic driving circuit.

●Paired Use: Recommended to order in pairs (transmitter + receiver). Factory sensitivity pairing ensures transit time measurement accuracy.

●Installation and Sealing: Ensure proper sealing between the threaded flange and pipeline interface during installation to prevent high-pressure leakage. The cable outlet should be protected against water and dust ingress.

●Temperature Shock Caution: Although the operating temperature range is wide, when experiencing rapid temperature changes (e.g., quick cooling from 280°C), gradual transition is recommended to prevent thermal stress damage.

●Customization Support: Custom versions with different frequencies (e.g., 40kHz, 125kHz), different pressure ratings, and housing materials (e.g., stainless steel, Hastelloy) are available. Please contact us for inquiries.
