1. How much is an ultrasonic electromagnetic flowmeter?
The price range of ultrasonic electromagnetic flowmeters is relatively large, and the core influencing factors include brand, specifications, functions, range caliber, etc. The specific price range ranges from 285 yuan to tens of thousands of yuan. Price reference for mainstream products on sale - Basic universal type: such as spot wholesale ultrasonic water meter, priced at about 285 yuan/unit, suitable for measuring water flow in conventional small-diameter pipelines - High cost-effective industrial type: spot universal ultrasonic electromagnetic flowmeter, priced between 180-2250 yuan/unit - Anti corrosion customized type: intelligent electromagnetic flowmeter for wastewater slurry and sewage scenarios, DN50/100 specification, priced at about 379.5 yuan/unit - Imported brand type: US Weidun VTON imported model, DN1-1000 full specification coverage, priced at 1760 yuan/unit - High precision explosion-proof type: fixed external clamp wall hanging explosion-proof model, can measure liquids, gases, and oils, priced at about 1121 yuan/unit 2 The price influencing factors indicate that the functional differences of different products will significantly affect the selling price: models with remote digital display, anti-corrosion and explosion-proof, large caliber customization, and imported brands will be several times more expensive than the basic model.

2. Types and Differences of Flowmeters
Flowmeters are mainly divided into volumetric, velocity, differential pressure, mass, and other categories based on their measurement principles. The core differences lie in their working principles, applicable media, and accuracy characteristics.
. 1. Working principle of volumetric flowmeter: The fluid is divided into fixed volume units by mechanical measuring elements, and the flow rate is calculated by counting the number of units. Representative types: elliptical gear, waist wheel, scraper flowmeter. Applicable medium: high viscosity liquids (such as oils, chemical reagents). Accuracy: ± 0.2%~± 0.5% (higher). Characteristics: Sensitive to changes in fluid viscosity, filters need to be installed to prevent jamming. Working principle of velocity flowmeter: flow rate is derived by measuring fluid velocity, usually requiring matching pipeline size data. Representative type: • Electromagnetic flowmeter: Based on Faradays law of electromagnetic induction, it measures conductive liquids (such as water, acidic and alkaline solutions) with an accuracy of ± 0.2%~± 0.5% and no pressure loss. Turbine flowmeter: By driving the turbine to rotate with fluid, it measures low viscosity liquids or gases (such as tap water and natural gas) with an accuracy of ± 0.5%~± 1%, requiring a straight pipe section. • Ultrasonic flowmeter: uses the time difference of sound waves propagating in the fluid to measure speed, suitable for large-diameter pipelines (such as municipal water supply), with an accuracy of ± 1%~± 2%, and can be externally clamped.3. Differential pressure flowmeter working principle: Based on the Bernoulli equation, the flow rate is calculated by measuring the pressure difference before and after the throttling element. Representative types: orifice plate, V-cone, Venturi tube. Applicable media: steam, gas, liquid (widely us
