1. How much does an ultrasonic meter cost? The price of ultrasonic meters varies greatly, ranging from a few hundred yuan to several hundred thousand yuan, depending on their type, function, brand, and accuracy. The following are the price references for the main types:
1. Ultrasonic flowmeter economy/basic type: The price is usually in the range of 2000-8000 yuan. For example, the integrated external clamp type or open channel flowmeter is suitable for measuring simple media such as clean water and has a relatively single function. Mid end industrial type: The price range is between 8000-30000 yuan. Most of them are external clamping or insertion type, with more abundant functions (such as signal transmission hole socks, data recording), higher accuracy, and suitable for various liquids. High end/precision type: The price can range from 30000 yuan to over 100000 yuan, used for industrial measurement with high precision and complicated working conditions. Ultrasonic thickness gauges have a wide price range, from a few hundred yuan to tens of thousands of yuan. For example, ordinary digital display models cost around 1200-2500 yuan, while professional models with more comprehensive functions and higher accuracy can be priced at over 3000-5000 yuan. Other specialized ultrasonic measuring instruments have extremely high prices for some highly specialized equipment. For example, the price of a pile ultrasonic testing instrument used for engineering quality inspection can reach tens of thousands of yuan (such as 90000 yuan), while the price of an industrial ultrasonic imaging analyzer can even reach 550000 yuan.
2. What is the installation and positioning distance of the sensor for the ultrasonic flowmeter?<
The installation and positioning distance of the sensor for the ultrasonic flowmeter needs to be determined based on the flowmeter type, pipeline parameters, and upstream and downstream pipe conditions. The core is divided into two categories: the requirements for the upstream and downstream straight pipe sections and the installation distance of the sensor itself. The reference requirements for mainstream types are as follows.
.1. Clamp on ultrasonic flowmeter (external universal type) 1 Requirements for upstream and downstream straight pipe sections: Under standard non turbulent flow conditions, the upstream straight pipe section should be ≥ 10 times the inner diameter of the pipeline (10D), and the downstream straight pipe section should be ≥ 5D. If there are turbulence components such as elbows, valves, pumps, etc. upstream, the upstream straight pipe section should be raised to 15D~20D, and the downstream should be maintained at ≥ 5D. If a rectifier is installed inside the pipeline, the upstream and downstream straight pipe sections can be shortened to within 5D. 2. The installation spacing of the sensor itself is divided into three installation methods: Z-type (direct penetration), V-type (one-time reflection), and W-type (two reflections). The conventional incidence angle value is 30 °~45 °, and the sensor spacing needs to match the pipe diameter and incidence angle. Taking DN100 pipeline as an example, the V-type installation spacing is about 0.5m~0.9m, which is subject to the manufacturers calibration parameters.
