Explosion-proof float liquid level gauge is maglev ball measuring element, through the magnetic coup…

Products overview:

ZW - UQZ seriesExplosion-proof float liquid level gaugeIs a kind of plug-in liquid level meter, it is by the dry reed pipe, resistance and enlarge transform circuit.When the level of magnetic magnetic float to a place of dry reed pipe, the dry reed pipe closed, to enlarge transform circuit output and the measured liquid level height corresponding to the current value, with the change of the liquid level height, convert liquid level height into linear amplification transform circuit of 4 ~ 20 madc signal output, in order to realize transmission and control of liquid level signal.

Second, the working principle:

ZW - UQZ series explosion-proof float liquid level gauge is composed of floating ball, rod and so on.By connecting flange to install on the top of the container, floating ball according to the principle of solid liquid phase volume, and so on floating in the liquid level, when the container when ball float liquid level change with the move up and down, because the magnetic effect, float level gauge of reed by magnetic suction, the liquid level position change into electric signal, through the actual location of the liquid display instrument with digital display, remote monitoring and control so as to achieve the liquid surface.

Applications:

ZW - UQZ series explosion-proof float liquid level gauge has a simple structure, convenient debugging, good reliability, high precision etc.Widely used in high temperature and high pressure, viscous, smudgy medium, such as asphalt, containing wax oil and inflammable, explosive, corrosive medium such as continuous measurement of liquid level (world).Can be used in oil, chemical raw materials storage, industrial process, biochemical, pharmaceutical, food and beverage, the terminal and gas station underground inventory level industrial measurement and control of various kinds of tank.Is near, water, reservoir water level monitoring and sewage treatment and so on.

Four, the main features:

1, suitable for liquid level of liquid in the container medium, interface measurement.In addition to the instructions, also can match remote transmitter, switch, detection alarm function is complete.

2, new instructions, intuitive reading and eye-catching, observing the direction of the indicator can be based on user need to change the point of view.

3, large measuring range, is not restricted by storage tank height.

4, indicating device, and is completely isolated measured medium, good sealing, high reliability, the use of safe.

5, simple structure, convenient installation, convenient maintenance, corrosion resistance, no power, explosion-proof.

6, environment temperature: - 40 ~ 80 ℃;

7, working temperature: - 20 ~ 120 ℃;

8, nominal pressure: 1.6 MPa or less;

9, flange standard: A: JB/T82.1-94 (flat flange) DN100 PN1.6 ball phi 90;

B: JB/T82.1-94 (flat flange) DN80 PN0.6 ball phi 76 medium density: acuity 0.65 g/cm3.

10, medium viscosity: 0.015 PaS or less;

11, liquid material: stainless steel;

12, explosion-proof grade: EX Ⅱ BT4.

Six, level gauge installation instructions:

1, ZW - UQD - 91 type instrument.

2, should not be measured medium containing ferromagnetic impurities.

3, in order to prevent the transport float in a sealed tube on the slide or collision, cause measuring tape out, the meter before they go out, use clamp to fix floating ball in the seal at the bottom of the tube, magnet steel on the top of the sealing tube.Users should be down clamp before install and use, will float up to sealing pipe top, then gently to float down, should make the corresponding rotational beard needle.

4, the face of the instrument instructions for pointer, full instructions digital measurement for gel injection direction is arranged, when an empty measure indicator for inverse direction when the needle.

5, instrument factory with flange installation, the user should match pipe flange.

6, instrument installation position generally choose the half range.

Seven, four types of installation:

A: B: overhead installation side side mounted C: side bottom mounted D: support installation

(when placing order, please indicate the type of installation and long length L value.)For exposure or non-metallic containers, can be used in a scaffold installations.For exposure or non-metallic containers, can be used in a scaffold installations.

Eight, installation and debugging matters needing attention:

1, the overall debugging

Ball float liquid level meter factory after calibration qualified together with hoop belt, user before installation can be carried out overall debugging (mobile magnetic float components, the display shows location should correspond to the transmitter output)

2, separate debugging

Transmitter can be removed from the UQZ type liquid level meter, using the zero mark of magnetic floating ball in the transmitter and the output should be 4 ma, in the magnetic steel under full marker for 20 ma output at this time, if zero full error, can adjust potentiometer zero potentiometer and scope, the laser particle size instrument after adjustment until to conform to the technical conditions, set to again after strong on the outside of level gauge body tube must pay attention to the level of the center line of the connecting flange must display scale zero alignment and transmitter output zero mark.

Nine, install and use notice:

1 float liquid level gauge shall be installed in the float up and down the location of the unhindered.

2 should not be measured medium containing ferromagnetic impurities.

3 in order to prevent the transport UQZ - D type instrument float in a sealed tube on the slide or collision, cause measuring tape out, the meter before they go out,

4 use clamp to fix floating ball in the seal at the bottom of the tube, steel in a sealed tube top.Users should be down clamp before install and use, will float up to sealing pipe top, then gently to float down, should make the corresponding rotational beard needle.

Pull the 5 float liquid level gauge face is pointer type, full instructions digital measurement for gel injection direction is arranged, when an empty measure indicator for inverse direction when the needle.

6 float liquid level gauge factory with flange installation, the user should match pipe flange.
