1. Ultrasonic flowmeter parameters
The core parameters of an ultrasonic flowmeter include measurement accuracy, repeatability, measurement range, flow rate range, operating temperature, pressure level, signal output, and communication protocol. These parameters directly affect the performance and applicable scenarios of the instrument. 1. Performance parameter measurement accuracy: usually ± 0.5%~± 1.0%, high-precision models can reach ± 0.2% repeatability: generally ± 0.1%~± 0.3%, better than accuracy indicators measurement range: pipe diameter covers DN15~DN6000, suitable for various pipeline sizes flow rate range: -32m/s~0~+32m/s (two-way measurement first band), specific models can reach 40m/s. 2. Operating parameters working temperature: -40 ℃~+200 ℃ (standard type), high temperature type can reach+400 ℃ Pressure level: PN16~PN420, high pressure type supports 25MPa or above Protection level: IP65 (Xiqin Qing dustproof and waterproof), IP67 (anti immersion), IP68 (submersible type) Medium requirements: turbidity<10000mg/L, bubble content<2% (Affects measurement accuracy) 3 Output and communication signal output: 4-20mA analog output, pulse/frequency output, switch alarm output Communication interfaces: RS-485 (Modbus, HART), PROFIBUS-DP, Ethernet interface Power supply: DC 8-36V or AC 85-265V, low-power battery power supply up to 5 years Installation and environmental sensor types: external clamp type (non-contact), plug-in type (drilling installation), pipe section type (flange connection). Installation requirements: The front and rear straight pipe sections must meet the requirements of front 10D and rear 5D (D is the pipe diameter). Environmental temperature: -30 ℃~+70 ℃ (working temperature of electron
