2、5 Common Faults and Solutions for the BST-100 Ultrasonic Flow Sensor

During long-term use，the BST-100 ultrasonic flow sensor may encounter various fault issues。The following are 5 of the most common problems and their solutions，helping business evaluation personnel quickly judge and handle them。1. Unstable measurement data：It may be caused by air bubbles or impurities in the pipeline，it is recommended to check pipeline cleanliness and install a filter；2. Insufficient signal strength：Check whether the sensor installation position is accurate，and ensure close contact with the pipe wall；3. No reading on the display：Check whether the power connection is normal，and replace the power module if necessary；4. Large measurement error：It may be caused by improper sensor parameter settings，recalibration is recommended；5. Frequent device crashes：Check whether the firmware version needs to be upgraded，or contact the manufacturer for professional repair。

3、Comparative Analysis of Technical Performance and Parameters

To help business evaluation personnel better select suitable products，we conducted a detailed comparison of the technical parameters of mainstream ultrasonic flow sensors such as BST-100，ZFD-100FB，HZ-100A/B and others。BST-100 adopts advanced digital signal processing technology，with measurement accuracy up to ±0.5%，far higher than the industry average；ZFD-100FB performs outstandingly in anti-interference capability，making it suitable for complex industrial environments；the HZ-100A/B series is known for its high cost performance，and is an ideal choice for small and medium-sized enterprises。All products of Xi'an Shenghongchuang Instrument Co., Ltd. comply with ISO 9001 quality management system certification，ensuring the reliability and stability of every device。

4、Procurement and Model Selection Guide

When selecting an ultrasonic flow sensor，business evaluation personnel need to consider multiple factors，including measurement medium，pipeline material，flow range，ambient temperature and others。For corrosive media，it is recommended to choose the BST-100A model，whose special material can effectively resist corrosion；for high-temperature environments，TOP-UFH86 is a good choice，with an operating temperature range of -40℃~150℃。In addition，it is also necessary to consider whether the installation method（wall-mounted or handheld），output signal type（analog or digital）and communication protocols（Modbus，HART and others）are compatible with existing systems。Xi'an Shenghongchuang Instrument Co., Ltd. provides professional model selection consulting services to help customers choose the most suitable products。

5、Common Misconceptions and FAQ

In practical applications，many users have some common misconceptions about ultrasonic flow sensors。For example，they believe that all models are suitable for any medium，but in fact，different models have significant differences in adaptability to different media；another example is ignoring the importance of regular calibration，which leads to a gradual decline in measurement accuracy。In response to these issues，we have compiled some common FAQs：Q1：Does the BST-100 require regular maintenance？A1：It is recommended to perform inspection and calibration every 6 months；Q2：Can the ZFD-100FB be used for gas flow measurement？A2：Yes，but a dedicated gas measurement model must be selected；Q3：How long is the service life of the HZ-100A/B？A3：Under normal operating conditions，its service life can reach 8-10 years。
