1. Product Basic Information

1.1 Product Classification

Ultrasonic flowmeter belongs to the category of flow measurement instrument, and the subdivided field is non-contact flow measurement equipment, which can be further divided into portable ultrasonic flowmeter, fixed ultrasonic flowmeter, insert ultrasonic flowmeter, etc., which is widely used in water industry, petrochemical industry, electric power, metallurgy and other industries in liquid flow monitoring scenarios.

1.2 Product Description

This product operates on the time-of-flight principle of ultrasonic propagation. By transmitting and receiving ultrasonic signals through sensors, it calculates fluid velocity and converts it into flow rate. Its core function enables non-invasive flow measurement for various liquids including water, crude oil, and chemical solutions. Positioned as an industrial-grade precision measurement device, it meets diverse application requirements such as production monitoring, energy billing, and process optimization. The installation and measurement process requires no pipeline modification, effectively reducing construction costs and downtime losses for users.

2.2 Product Introduction

This ultrasonic flowmeter is designed with the philosophy of "precise measurement, easy installation, and stable operation." Its core value lies in providing industrial enterprises with comprehensive, low-cost flow monitoring solutions that address the pain points of traditional contact-type flowmeters-complex installation, susceptibility to medium corrosion, and high maintenance costs. The product employs time-of-flight measurement technology, where two ultrasonic sensors alternately transmit and receive signals. By analyzing how fluid flow affects ultrasonic propagation time, it calculates flow velocity and converts it into instantaneous and cumulative flow rates using parameters like pipeline diameter and medium density. Its applications span water supply network monitoring, refined oil transportation measurement in petrochemical plants, circulating water flow control in power plants, and cooling water velocity detection in metallurgical industries. This system not only provides data support for production process optimization but also meets the precision measurement requirements for energy consumption statistics and trade settlements. Tailored to different user scenarios, it can be flexibly configured with portable detection modules, fixed monitoring terminals, and cloud-based data management systems, achieving integrated services from single-point measurement to comprehensive monitoring.

8. Frequently Asked Questions (FAQ)

8.1 Technical issues

Q1: Can ultrasonic flowmeter measure gas medium?

A1: This product is specifically designed for liquid media and cannot directly measure gas. For gas flow measurement, please consult our company's dedicated gas ultrasonic flowmeter series.

Q2: Will bubbles in the pipeline affect the measurement accuracy?

A2: A small amount of bubbles has little effect. If the bubble content exceeds 5%, the signal attenuation will affect the measurement accuracy. It is recommended to set up an exhaust device at the high point of the pipeline, or choose a customized model with bubble compensation function.

Q3: How to determine whether the sensor installation position is appropriate?

A3: The installation location should avoid disturbed areas such as pipe elbows, valves, and pump bodies. Ensure that the straight pipe sections before and after meet the requirements of "10 times the pipe diameter before and 5 times the pipe diameter after", and avoid direct sunlight and strong electromagnetic interference sources.

8.2 Operational Issues

Q1: What causes the device to display "No signal"?

A1: The sensor may be loose, dirty, or improperly installed. Check the cable connection, clean the sensor surface, and reconfirm the installation position.

Q2: How do I export data from the device?

A2: Two methods are supported: either export directly to the host via USB port (in Excel format) by inserting a USB drive, or remotely transfer to a computer or cloud platform through RS485 or 4G modules.

Q3: What if the battery life of a portable device is insufficient?

A3: The device supports replaceable lithium battery (requires original parts) or external power supply. For daily use, enabling the automatic sleep mode helps extend battery life.

8.3 Business-related issues

Q1: Can the product issue a VAT special invoice? A1: Yes, please provide complete billing information (company name, taxpayer identification number, address and phone number, bank account) when placing the order. The invoice will be issued within 1-3 working days after shipment.

Q2: Does the product support trial? A2: Yes. For bulk purchase customers (≥10 units), you can apply for a 7-day trial. If no damage occurs during the trial period, the full refund or discounted purchase is available.
