    LZ series intelligent Metal tube floater flowmeter is a variable area flowmeter which is based on the floater position measurement.It adopts full metal structure, which is with the features of small volum, low pressure loss , big range ratio(10~20:1), optional transmitter with HART communication function and installation and maintance convenient.It is widely used in various industries under the complex and bad environment, which is measuring the flow and controling the process to the small flow and low flow velocity, and all kinds of harsh conditions of medium.

    LZ series intelligent metal tube floater flowmeter series products, according to different users’ requirements and different occasions, there are many kinds of measurement form for users to choose; According to the output form, there are on-site instruction type, far transmission type, control alarm type; according to the requirements of explosion-proof, it can be divided into three types: the common type, intrinsic safety type, isolation and explosion-proof type.

    LZ series intelligent metal tube floater flowmeter adopts the international advanced Honeywell without contact and no hysteresis detecting changes in the Angle of magnetic field of magnetic sensor, and with high performance MCU, which can realize LCD display:the instantaneous flow, total flow, loop current.environment temperature, damping time, small signalremoval.Optional 4~20mA tranmission(with HART communication), pulse output, high and low limit alarm output function, etc, the type of intelligent signal transmitter has high precision and reliability, which can fully replace the same type imported instrument, and it also has high price performance, parameter standardization online and power failure protection, etc features.

    LZ series intelligent metal tube floater flowmeter’s design also takes into account the users’requiremnts of the process flow , there are five installation types to select: lower inlet on the installation type, upper inlet under the installation type , side in side out installation, bottom in side the installation type and horizontal type installations.

    2. Structure and Principle

    LZ series intelligent metal tube floater flow meter is made up of two parts:

    (1)Sensor - measuring tube and floater;

    (2)Signal transmitter - indicator;

    The sensor has four connecting liquid material :stainless steel, Hastelloy, Titanium, stainless steel lining FEP; The users can choose different touching liquid material to meet the needs of the proof pressure of process and anti-corrosion of medium according to the requirements of the different process pressure and corrosive medium.According to the different measurement requirements, the users can choose different indicator combination in their selection to realize the different measurement requirements. The specific indicator form and its corresponding function, please refer to the indicator table.

    Flow rate is measured by the indicator in the transmitter through the coupling of magnetic steel feeling floater’s position changes to complete the flow indicator and signal remote transmission. When the measured medium flowing through the measuring tube from bottom to top, the floater by gravity, buoyancy and fluid velocity to the floater’s vertical upward thrust are balance, floater will be relatively static in a certain position, the position changes with the floater and taper pipe ring gap area and fluid velocity, the position of the floater is corresponding to the size of the measured medium flow.

    3.Product Features:

    ▉ Strong metal structure design

    ▉ Suitable for various industries of gas and liquid measurement

    ▉ New flow shell structure design, it can be used in high temperature environment without increasing components.

    ▉ Special design of conical measuring tube, its measuring range and measuring linear are wider and better.

    ▉ We can offer flange connection, clamp, thread and other process connection modes, which is suitable for most of the factories application requirements

    ▉ Measuring part materials can be selected: stainless steel, titanium, Hastelloy, PTFE, FEP, etc

    ▉ A specially designed magnetic coupling system, can improve the measurement precision and stability obviously .

    ▉The features of far transmission output of the instrument:

    1.The Large LCD display can display the instantaneous flow and total flow at the same time and also display the instantaneous flow simulation.

    The upper display the instantaneous flow, lower display the total flow

    The instantaneous flow range: 0.000-99999

    Cumulative flow display range: 0.00-99999999

    Current display range: 3.80-21.00 mA

    Instantaneous flow percentage display: 0-100%

    The pointer Angle range: 0.00 to 90.00 °

    Ambient temperature range: - 20 - + 80 ℃

    The cumulative small signal removal range: 0-10%

    Damping time setting range: 0 to 10 seconds

    A variety of optional instantaneous flow and total flow unit, after the the unit switching, the range is automatic conversion.

    2.The upper can be switched on the display: the instantaneous flow , loop current, percentage of the instantaneous flow and cumulative small signal removal, damping time, the current environment temperature, and the pointer rotation angle, etc information, and it also can display the commonly used symbols and engineering units, which will not affect the discharge total flow and instantaneous flow simulation of the display at the time.

    3.The LCD displays the flow range of the instantaneous flow , according to the measurement medium at the scene, it can be corrected .

    4.Double LCD display’s power consumption is microamps level, which meets the requirements of the instrinsic safety explosion-proof.

    5.Accuracy: <+/-0.5%, the temperature drift: <+ /- 0.1%/ 10 ℃

    6.Perfect power-failure protection function, when the power failure, it can save the current total flow (the total flow of sampling period is 0.3 S), and applied the advanced six levels of data backup mechanism, which makes the data loss impossible.

    7.LCD can select the backlit display

    8.Transmitter can output: two-wire system, 4-20 mA signal, and has nothing to do with the LCD display function whether it has or not.

    9.Support the battery power supply function, it uses different types of rechargeable batteries according to different application, and it can be normal work 3 to 12 months at one time charging.

    10.It is no need to open the cover, it uses the magnetic pen operation way and also keep the normal buttons. (it can be made according to customers’ requirements)

    11.By HART protocol and the upper computer software or hand-held communication. Upper computer connects with the meter by using HART modem, which can dynamically monitor the instantaneous flow and total flow, loop current , percentage of the instantaneous flow, etc(only for two-wire system, 4-20 mA instrument with HART communication function)

    12.By HART protocol, hand-held or upper computer software can be used to the operation of the flowmeter for some or all of the configuration (only for two-wire system 4-20 ma instrument with HART communication function)
