1Thermal oil orifice flowmeterFeatures:
The structure of the throttling device is easy to replicate, simple and sturdy, with stable and reliable performance, long service life, and low price.
▲ Calculation of orifice plate adopts standards and processing
▲ Wide application range, all single-phase flows can be measured, and some mixed phase flows can also be applied.
The standard throttling device does not require real flow calibration and can be put into use.
The installation of integrated orifice plates is simpler, without the need for pressure pipes, and can be directly connected to differential pressure transmitters and pressure transmitters.
Intelligent features
▲ Adopting imported monocrystalline silicon intelligent differential pressure sensor
▲ High precision, comprehensive self diagnostic function
The range of the intelligent orifice flowmeter can be self programmed and adjusted.
▲ It can display cumulative flow rate, instantaneous flow rate, pressure, and temperature simultaneously.
▲ In addition to online and dynamic full compensation functions, it also has self diagnosis and self setting range.
▲ Equipped with multiple communication interfaces
▲ High stability
▲ Wide range, greater than 10:1
Intelligent technical indicators
▲ High precision: ± 0.075%
▲ High stability: better than 0.1% FS/year
▲ High static pressure: 40MPa
▲ Work continuously for 5 years without the need for calibration
▲ Temperature and static pressure effects can be ignored
▲ Anti high overvoltage
