Introduction

In the field of flow control equipment, JY-TUFB and JY-TUFR, as two mainstream wall-mounted ultrasonic flow sensors, have performance differences that directly affect corporate purchasing decisions. This article compares and analyzes the performance of the two products in key indicators such as accuracy, stability, and environmental adaptability through actual testing, helping you choose the most suitable ultrasonic flow sensor solution.

Core Technology Comparison Between JY-TUFB and JY-TUFR

The core technology of ultrasonic flow sensors directly affects their measurement accuracy and stability. JY-TUFB adopts the Doppler effect principle and is suitable for liquid measurement containing bubbles or particles, while JY-TUFR is based on the transit-time method and is more suitable for high-accuracy flow monitoring of clean liquids. These two technical approaches each have their own advantages in industrial scenarios:

• JY-TUFB: The signal processing algorithm is optimized for turbid media and performs outstandingly in scenarios such as wastewater treatment and mining slurry
• JY-TUFR: Adopts dual-channel cross-verification technology, and in clean fluids such as chemical raw material conveying and food and beverage applications, the error can be controlled within ±0.5%

Test data from Xi'an Shenghongchuang Instrumentation Co., Ltd. show that under the same operating conditions, the repeatability error of JY-TUFR is 0.3 percentage points lower than that of JY-TUFB, which is directly related to its use of imported German piezoelectric ceramic transducers.

Structural Design and Installation Adaptability

As wall-mounted ultrasonic flow sensors, the two products have significant differences in mechanical structure:

The reinforced stainless steel housing of JY-TUFR gives it a longer service life in high salt spray environments such as coastal areas, while the compact design of JY-TUFB is more suitable for retrofit projects with limited space. It is worth noting that both products are compatible with the LRF-3000 series handheld ultrasonic transmitters, making on-site calibration convenient.

Measured Analysis of Key Performance Indicators

Accuracy and Stability Testing

In the ISO 4064 standard test environment, we compared the continuous 30-day operating data of the two sensors:

• Under normal-temperature clean water conditions, the daily average fluctuation amplitude of JY-TUFR is only 0.2%, better than JY-TUFB's 0.35%
• When the medium temperature rises to 80℃, JY-TUFB, due to its built-in temperature compensation algorithm, keeps the accuracy deviation within 0.8%, while JY-TUFR reaches 1.2%
• In slurry testing with a 10% solids content, JY-TUFB still maintains a measurement accuracy of 1.5%, while JY-TUFR shows a deviation of 2.3%

These data confirm JY-TUFB's adaptability advantage in complex media, while JY-TUFR is more suitable for clean fluid metering with stringent requirements.

Environmental Adaptability Verification

By simulating different industrial environments, we found:

1. Electromagnetic interference test: In a strong electric field of 30V/m, the shielding design of JY-TUFR reduces its signal attenuation by 40% compared with JY-TUFB
2. Vibration test: The damping structure of JY-TUFB makes its reading fluctuation amplitude 60% lower than JY-TUFR under 50Hz mechanical vibration
3. Low-temperature startup: In a -20℃ environment, JY-TUFR can complete self-check within 30 seconds by virtue of its heating module, while JY-TUFB requires 2 minutes

These characteristics make JY-TUFR an ideal choice for explosion-proof areas such as petrochemical industries, while JY-TUFB performs better in vibration environments such as mining and metallurgy.

Selection Recommendations and Industry Applications

Based on Xi'an Shenghongchuang's 15 years of industry service experience, we offer the following recommendations:

Scenarios Where JY-TUFB Should Be Preferred

When your application involves the following characteristics, the JY-TUFB wall-mounted ultrasonic flow sensor offers better cost performance:

• The medium contains suspended particles or bubbles of ≥5%
• Pipeline vibration intensity exceeds the GB/T 29531-2013 standard
• The budget is limited and ±1% accuracy is acceptable
• Compatibility with older model equipment such as FDT-25W is required

Scenarios Where JY-TUFR Should Be Preferred

The JY-TUFR solution is recommended in the following situations:

• Clean fluid metering requires accuracy above ±0.5%
• There is strong electromagnetic interference or explosion-proof certification is required
• It needs to form an intelligent monitoring network with the SCTU series
• The medium temperature is often below -10℃ or above 70℃
