Top mounted ball float liquid level gauge

• 

Top mounted ball float liquid level meter adopts 304 stainless steel, PVC, PTFE and other materials …

Products overview:

ZW - UQZ seriesTop mounted ball float liquid level gaugeBy the liquid level sensor and intelligent HART plate (current transformer) in two parts, floating ball and the changes of liquid level, control of dry reed pipe and disconnect, so that the internal resistance sensor into a linear change, again by converter to convert the change of the resistance to standard 4 ~ 20 ma current signal and superposition of HART digital signal output.Far eastone supply control room can realize the automatic detection of liquid level, control and record.The instrument applies to oil, chemical, power, light industry and pharmaceutical industry wastewater treatment and various atmospheric pressure and pressure containers within the medium level measurement, especially for the underground storage tank, storage tank level measurement zui to ideal.

Second, the working principle:

ZW - UQZ series top mounted ball float liquid level gauge is mainly composed of maglev ball, sensor and transmitter of three parts.When maglev ball change with the liquid surface, floating up and down along the tube, floating ball in the magnetic steel and sensors in the corresponding position of dry reed pipe sensor is a change in the total resistance by the transmitter will change again after the resistance of the signal is converted into 4-20 ma electrical signal output, and through the digital display control instrument or column display device to remote measurement of liquid level, and on the display set upper and lower limit alarm, realize remote digital control of liquid level.Can also be composed of other regulator level constant value control computer control system, realize the PID for remote control of the liquid level.

Applications:

ZW series - UQZ top mounted ball float liquid level gauge is suitable for the oil refining industry, chemical industry, paper making, food and pharmaceutical industries, and applicable sewage and all kinds of exposure or pressure containers within the medium level measurement, for underground storage tanks and high-level water tank level measurement is the ideal instrument.

Special supply ￠56 (guide for ￠12);￠29 (guide rod is ￠7.5).

10, working voltage:, dc 24 v, 5 a.

Six, four installation level score below:

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.

Seven, notable matters of installation:

1, the instrument 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 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.

Instructions:

1, key operation:

if2Within minutes without any button press, transmitter keys locked automatically, if you want to operate, need to open again.The above operation, the use of the zero key 【Z", the full key"S】 can be realized, and the two key transmitter board the above instructions.Without a header display external current meter can also achieve adjustment.
2, measuring parameter Settings:
