Definition and Overview

The BF-LBY handheld ultrasonic transmitter is a non-contact flow measurement device based on the Doppler effect principle，designed specifically for complex operating conditions in industrial environments。By transmitting high-frequency sound waves and receiving signals reflected by particles or bubbles in the fluid，the device accurately calculates flow velocity and flow rate。Compared with traditional mechanical flowmeters，BF-LBY requires no pipe cutting or process interruption，making it especially suitable for measuring corrosive，high-temperature，or high-pressure media。Xi'an Shenghongchuang Instrumentation Co., Ltd. adopts military-grade sealing technology and a 316L stainless steel housing，enabling a protection rating of IP68 and stable operation within an extreme temperature range of -40℃ to 150℃。

Industry Background and Market Analysis

According to the 2023 Global Industrial Sensor Market Report，the penetration rate of ultrasonic flow measurement equipment in fields such as petrochemicals and wastewater treatment has achieved an annual growth of 12.7%。These scenarios commonly involve challenges such as strong acids and alkalis，as well as high-viscosity fluids，while the BF-LBY series significantly reduces the interference of media characteristics on measurement through adaptive signal filtering technology and a dual-probe design。Compared with similar products such as HQTDS-100H，BF-LBY can still maintain an error range of ±1% in slurries with a solids content exceeding 5%，an advantage that has enabled its wide application in industries such as mining and papermaking。As a national high-tech enterprise，Xi'an Shenghongchuang has developed derivative models such as DN-100B and ZFD-100P，which have passed SIL2 functional safety certification，further strengthening its competitiveness in the market for special operating conditions。

Technical Performance and Parameter Comparison

Application Scenarios in Special Environments

In high-temperature heavy oil pipelines of refineries，the ceramic sensor probe of BF-LBY can withstand an instantaneous high temperature of 300℃，and its patented heat dissipation structure avoids the signal drift problem commonly seen in similar products such as ZFD-100H。For hydrofluoric acid transfer pipelines in chemical plants，the device uses a PTFE anti-corrosion coating，combined with the explosion-proof housing of the BF-LBS model，perfectly solving the measurement challenges in highly corrosive environments。A coastal nuclear power project case shows that in a circulating cooling water system containing salt mist，BF-LBY operated continuously for 8000 hours without failure，far exceeding the requirements of the International Electrotechnical Commission IEC60751 standard。
