1. Wiring diagram of ultrasonic flowmeter
Ultrasonic flowmeter wiring is mainly divided into two parts: host wiring and probe wiring. There are differences between different brands and models, and it is necessary to follow the product manual for accuracy. 1. Power input for host wiring: Supports AC 220V or DC 24V power supply. Choose one of them according to the wiring diagram. Sensor interface: - Downstream probe connected
1.
2. Terminal 3 (GND, DN -, DN+), usually only need to be connected to DN - and DN+(terminals 2 and 3) - Upstream probe connected
4.
5. Terminal 6 (GND, UP -, UP+), usually only need to be connected to UP - and UP+(terminals 5 and 6) 4-20mA output: AO terminal connected to signal positive pole, 24V - terminal connected to signal negative pole 485 communication: connect 485 OUT A and 485 OUT B terminals Heat meter function: - Water supply terminal connected to TX

1. GND - Return terminal TX
2. T
2. GND (supply and return GND are connected together) Relay output: Connect RELAY+and RELAY - terminals 2. Probe wiring Probe cables usually include shielded wires, signal positive (+) and signal negative (-) terminals. Conventional connections only require connecting the+and - terminals, and shielded wires can be omitted. Due to possible differences in terminal definitions and wiring methods among different manufacturers, please make sure to check the wiring diagram provided in the instruction manual before actual wiring.
2. How much does an ultrasonic electromagnetic flowmeter cost?
The price range of ultrasonic electromagnetic flowmeters is large, and the core influencing factors include brand, specifications, functions, range and caliber. 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.3. Imported brands of wedge-shaped flowmeters
The main imported brands of wedge-shaped flowmeters include Emerson, Siemens, Weidun from the United States, Lite On from Germany, and Konko from the United States, each with their own focus on accuracy, stability, and industry applications.
. 1. Brand List Emerson (USA): Its Rosemount series is the industry benchmark, with high pr
