ZW3051LDP series Double flange remote liquid level meter ；驊腋∥锏某恋硇越橘|(zhì)強腐蝕或劇毒性介質(zhì)可消除導壓管泄漏污染周圍環(huán)境現(xiàn)象的發(fā)生：可免去采用隔離液時，因測量信號的不穩(wěn)定，需要經(jīng)常補充隔離液的繁瑣工作。">Mainly used for measuring the following occasions: precipitation medium strong corrosive or toxic medium viscous medium under high temperature and crystallization of the medium with solid particles or suspended solids can eliminate the pipe leakage phenomenon: the pollution of the environment to be isolated by liquid, because the measurement signal is not stable, often need tedious work supplementary isolation liquid. ，從而使測量結(jié)果真實地反映過程變化的實際情況。">A continuous measurement of the interface and density of remote device can avoid different instant mixing medium, the actual situation which makes the measurement results reflect the process of change.

、工作原理：">Two, work principle:

、低兩壓力室，作用在δ元件（即敏感元件）的兩側(cè)隔離膜片上

，通過隔離片和元件內(nèi)的填充液傳送到測量膜片兩側(cè)

。">ZW3051LDP series <strong> double flange remote liquid level gauge</strong> principle is when the measured medium pressure into two kinds of high and low pressure chamber two, role in the delta element (i.e. sensitive element) on both sides of the diaphragm, the spacer and components inside the filling liquid transferred to the measuring diaphragm on both sides. The liquid level transmitter is measured by the diaphragm and the both sides of insulation on the electrode sheet of each component of a capacitor. ，致使測量膜片產(chǎn)生位移，其位移量和壓力差成正比

，故兩側(cè)電容量就不等

，通過振蕩和解調(diào)環(huán)節(jié)，轉(zhuǎn)換成與壓力成正比的信號

。">When the pressure is inconsistent, resulting in measuring diaphragm displacement, the displacement and the pressure difference is proportional to the capacitance on both sides from it, through stages of oscillation and demodulation, signal into proportional to pressure.

，另一端接氣相時，根據(jù)流體靜力學原理

，有：">When the pressure gauge is connected to one end of the liquid phase, the other end of the air phase, according to the principle of fluid statics, have:

PB=PA+H p g (2-1)

；">Type: H - liquid height;

P - measured medium density;

By type (2-1) available:

P= PB PA= H p g

，被測介質(zhì)的密度和重力加速度都是已知的

，因此，差壓計測得的差壓與液體的高度H成正比

，這樣就把測量液體的高度的問題變成了測量差壓的問題

。">In general, the measured density and acceleration of gravity medium are known, therefore, the differential pressure gauge differential pressure and liquid measured the height of the H is proportional to the height of the problem of measuring the liquid into the differential pressure measurement.

Third, application:

，它與變送器之間是靠注滿流體的毛細管連接起來的

。">ZW3051LDP series <strong> double flange remote liquid level gauge</strong> is used to prevent the pipeline media directly into the transmitter in the sensor module, and it is filled with fluid between the transmitter by capillary connected. 、流量和壓力
