Name: VA 500 – Merilnik pretoka za stisnjen zrak in ostale pline.
Rating: 4.5 (364 reviews)

V nasprotju s prej uporabljanimi mostnimi tokokrogi, novo razvita elektronika za obdelavo vse merjene vrednosti shranjuje v digitalni obliki. To omogoča boljšo natančnost v primeru velikih merilnih obsegov 1…1000.

Vmesnik RS 485, Modbus-RTU kot standard
Integriran prikaz za m³/h in m³
Uporabne od 1/2“ do 12“ (DN 300)
Enostavna montaža pod pritiskom
Analogni izhod 4...20 mA za m³/h oziroma m³/min
Pulzni izhod za m³
Notranji premer nastavljiv preko tipkovnice
Ponastavljiv števec porabe
Možnost nastavljanja s tipkovnico na zaslonu: referenčni pogoji, OC in mbar, območje 4...20 mA, jakost pulza

Podrobnosti

Measurement of mass flow direct output of standard volume flow
Highly accurate at small as well as higher flow rates
Pressure and temperature compensated by the thermal mass flow principle
Quick and easy installation via a ½" ball valve
No moving parts, thus low maintenance
Vanishingly low pressure drop due to vanishingly low blockage of the diameter
Can be used for compressed air and non-corrosive gases such as nitrogen, oxygen, argon, helium, etc.

04...20 mA, pulse and a Modbus RTU (RS 485) interface as standard.
Optional: Interfaces such as Modbus TCP (Ethernet), PoE, M-Bus
Optional: Bi-directional measurement
Pressure tight up to 50 bar
Temperature range up to 110°C
Protection class IP65
Integrated display for showing the measured values
Can be used from 1/2" up to 40", larger diameters on request
Easy installation under pressure
Settings can be changed via the display
Main counter reading can be reset via the display
Suitable for gas velocities up to 224 Nm/s
Highly precise with an accuracy of ± 1.5% or ± 1% of the measured value ± 0.3% of the final value
