Ang SVH ay isang high-end vortex flowmeter para sa liquid, gas, at steam service, na may malawak na process envelope at isang separate converter option. Ang isang bluff body ay nag-shed ng alternating vortices habang ang fluid ay lumalampas; ang shedding frequency ay proporsyonal sa flow velocity. Ang body at bluff body ay gumagamit ng CF8 o CF8M stainless steel, fluid temperature range ay minus 40 hanggang 260 degrees C, at ang working pressure ay sumasaklaw mula minus 0.1 MPa hanggang flange rating.
Ang malawak na supply voltage na 10.5 hanggang 42 VDC ay nagpapahintulot sa SVH na mag-share ng parehong power source sa iba pang instrumento sa linya. Ang (4-20) mA DC two-wire analog output at HART communication signal ay nagpapasimple sa cabling sa mahahabang runs. Ang meter ay ipinadala sa integral o separate-sensor form, na may isang separate converter na naka-mount sa 2-inch pipe, at angkop sa process industries, chemical, power generation, water at wastewater, at oil at gas service.
Anong mga fluid ang maaaring i-meter ng SVH?
Ang SVH ay sumusukat ng liquids, gases, at steam. Iwasan ang multiphase flow at high-viscosity fluids na mag-da-damp sa vortex shedding.
Ano ang pagkakaiba ng SVH at iba pang vortex meters sa pamilya?
Ang SVH ay ang high-accuracy, wide-power-supply variant na may malawak na temperature range at isang separate converter option. Gumagamit ito ng CF8 o CF8M body material at isang malawak na DC 10.5 hanggang 42 V supply para sa flexible integration.
Anong pressure range ang sinusuportahan ng SVH?
Ang SVH ay rated para sa fluid pressure mula minus 0.1 MPa hanggang flange rating. Ang malawak na envelope ay sumasaklaw sa parehong vacuum service at high-pressure process lines, na may one-inch NPT internal thread cable gland bilang standard.
Paano nag-si-signal at nag-co-communicate ang SVH?
Ang analog output ay isang 4-20 mA DC two-wire signal; ang HART communication ay superimposed sa parehong pares ng wires, kaya ang parehong cable ay nagdadala ng power, output, at bidirectional configuration. Ang separate converter ay naka-mount sa 2-inch pipe kapag ang sensor ay naka-mount remotely.
