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. If you need an accurate quotation, it is recommended to directly contact the corresponding manufacturer or distributor for confirmation.
2. Upstream and downstream differentiation of ultrasonic flowmeter preamplifier
Ultrasonic flowmeter calculates flow rate by measuring the time difference between the propagation of sound waves in the forward and backward directions, and the upstream and downstream differentiation is crucial for measurement accuracy.
. 1. The core differentiation standard for ultrasonic flow meters is mainly based on the relative relationship between the sound wave propagation path and the fluid direction: • Upstream sensor: installed in the direction of the fluid source, where the sound wave is first emitted • Downstream sensor: installed in the direction of the fluid direction, receiving the sound wave signal emitted upstream. 2 Specific differentiation method 2.1 Physical installation location identification - View sensor housing identification: Most products will indicate "UPTREAM" (upstream) or "DOWNTREAM" (downstream) - Cable connection identification: Upstream sensors are usually connected to interfaces marked with "UP" or "In" on the host. 2.2 Sound wave propagation time verification: Installation correctness can be verified by measuring the propagation time in two directions: - Forward propagation time: upstream → downstream
