Target oil Flow meter summary EFT Electric Target Flow Transmitter is improved on the basis of DBLB Electric Target Flow Transmitter which is manufactured by our company. Still adopt the lever principle and stress measuring method in the transmitter part, directly measure the force applied to the target board in the liquid, acquires the signal being consistent with fluid flow rate change and being measured through high precision spectacles cantilever stress sensor., the measured signal is transferred into 4-20mA analog signal and output It features pretty external appearance as its fashionable shell structure design. This structure makes each chamber separately to make the meter more reliable and safe. Also the meter is added precise static pressure adjustment device so as to keep high precision and reliability. Both shell structure design and the static pressure adjustment device have been granted the national patents. The patent number for external appearance design: 99 3 21507.6; The patent number for static pressure adjustment device: 99 2 23728.9; Main Technical Parameters Operating voltage: DC24VOutput signal: 4-20mALoad Resistance: see the load characteristic curve;Precision: 1.0% FS( weighing method)Ambient temperature: -35-70Operating temperature:≤100(without heat sink) ≤400with heat sink The material of wetted part , measuring chambercarbon steel or 1Cr18Ni9Ti ,other :1Cr18Ni9TiPower supply inlet: M20×1.5(internal thread) Flange standard: JB/T82.1-942.5MPa JB/T82.2-944.0,6.4MPaProtection: IP65Damping: 0.21.67s(tunable)The ratio of measuring range: 31Operation principlesee the chart, the force generated by the flow of liquid, which forces on the target board.. the force with seal diaphragm as supporting point makes 1 lever to generate force which is inverse with current then transferred into 4-20mA DC.
