What is the difference between the output form of vortex flowmeter, on-site display and pulse output?
Display: Numerical values are displayed through on-site display units, such as LCD digital tubes. This method can only be viewed on site and cannot be read or calculated. Pulse: Cumulative flow is represented by pulses, for example, each pulse represents a simple 0.1 M3/H, so 10 pulses are 1 M3/H. This method requires a counter to accumulate.. Only able to calculate cumulative flow rate 4-20mA: can only represent instantaneous flow rate 4-20 represents 0-10 M3/h. If the current output is 12MA, then the instantaneous flow rate is 5 M3/h. This method can only calculate instantaneous flow rate and requires a transmitter to convert 4-20 into the required value. 2. Do vortex flowmeters need to be powered? Both powered and non powered vortex flowmeters exist, depending on their functional configuration. 1. Intelligent devices that require power must have an external power supply (such as 24V DC) for smart vortex flowmeters with built-in electronic components. The core function of such devices is to convert physical flow signals into standard current signals (such as 4-20mA) or digital signals (such as RS485), thereby achieving real-time interaction with external control systems, data recorders, or industrial IoT platforms. This type of application is currently the mainstream in the market, covering scenarios such as chemical engineering and energy monitoring of combustion sources that require remote monitoring. 2. Mechanical devices that do not require electrical connection use pure mechanical structures. Basic models usually rely only on fluid force to drive internal gears or finger liquid needles, achieving

The measurement range of vortex flowmeter is relatively wide and can be applied to flow measurement of various liquids and gases. However, the specific measurement range may vary due to factors such as measurement medium, pipe diameter, and environmental conditions. The following is a detailed introduction: Industrial water full tube vortex flowmeter is mainly used for flow measurement of small and medium pipe diameters, while plug-in vortex flowmeter can be used for flow measurement of large pipe diameter (DN ≥ 300mm) pipelines.. It is widely used in urban water pipelines and industrial water main pipelines of chemical, power, metallurgical, papermaking, chemical fiber and other enterprises, and can measure the circulating water, wastewater, waste reporting liquid, etc. in the production process. Corrosive liquids, such as sulfuric acid, hydrochloric acid, nitric acid, acetic acid, and various chemical solutions, can be accurately measured by vortex flowmeters. In recent years, vortex flowmeters with small diameters (DN ≤ 25mm) have become more suitable for measuring corrosive liquids. These flowmeters use compression molding technology, sensors are made of all plastic products, and are equipped with non-contact ultrasonic detection elements, achieving non-contact measurement of liquids. Electromagnetic flow meters dominate the flow measureme
