Products overview:

ZW series - LUSHMagnetoelectric Angle type flowmeterIs advanced magnetoelectric digital detection technology research and development of a new type of intelligent flow meter.Flowmeter by flow sensor and display (also called header) in two parts, the series of electromagnetic flow meter and flow meter in design took up two kinds of vortex flowmeter are products of their respective advantages, and combined with the actual situation of oilfield, foster strengths and circumvent weaknesses.

Second, the working principle:

ZW series - LUSH magnetoelectric Angle type flowmeter is based on the principle of the karman vortex street and Faraday electromagnetic induction principle, when conducting fluid through the body vortex, contains a strong lines of magnetic force line, can produce pulse electromagnetic induction electromotive force, relationship, as a function of pulse frequency of electromotive force and flow pulsation electromotive force detection to processing, can be realized for flow measurement.A weak electromagnetic signal after the preamplifier JingJian the amplifier amplification to the display unit.Display unit of the single chip microcomputer system operations according to measure the number of pulses, and show the instantaneous flow and cumulative total.

Three, structural components:

ZW series - LUSH Angle type magnetoelectric meter consists of two parts, sensor and converter, and integrating the flow measurement and local display, equipped with a variety of standard transmission signal interface.

Four, the main features:

1, double power supply design, internal 3 V ~ 3.6 V lithium battery or external 24 VDC power supply, also the power supply.

2, intelligent integrated design, powerful, the scene, according to the convenience of users read, convenient parameter modification.

3, the signal output function: comprehensive standard two wire system 4 ~ 20 ma output current, pulse output and the RS - 485 communication (optional).

4, with good resistance to vibration anti-interference ability.

5, sensor is made of stainless steel materials, corrosion resistance, no internal activity components, long service life.

6, minimum flow rate is low, than wide range, high precision measurement.

Five, the technical parameters:

1, the nominal diameter (mm) : DN25 ~ DN100;

2, nominal pressure (MPa) : the nominal pressure rating: 1, 1.6, 2.5, 4, 16, 25, 32, 35, 42;

3, precision grade: 1.0, 1.5;

4, range than: transcribed;Those days;

5, working voltage: (within) 2.7 V ~ 3.6 VDC;(outside) + 18 v ~ + 36 VDC;

6, the output signal: standard two wire 4 ~ 20 ma output current, pulse output;

7, communication interface: RS - 485, RS - 232 - c, MODBUS, REMOTE (HART).

Six, installation and use:

1, the Angle of the flowmeter shall generally be installed upright, straight-through flow meter can be horizontal, vertical (vertical flow shall be from bottom to top) or tilt installed on and its corresponding nominal diameter pipeline, and the casing on the arrow direction to the flow direction of medium and consistent.If straight-through flow meter should be installed vertically, should open the flow display, front cover, the panel and the LCD display turned 90 ° and the location of the readings.The work shall be carried out by on-site technical personnel, can be entrusted to the manufacturer to be modified before they go out.In order to facilitate the meter reading and reading, can be continuous flow display and four small screws removing the flow sensor, then flow meter display, forward or reverse turn 90 ° or 180 °) position, zui after screwing in small and fastening screw.Meter if installed in outdoor, obstructions to prevent sun, rain and pollution, install section may not have a strong vibration and strong magnetic field interference.

2, in order to guarantee the accuracy of the measurement, should be not installed in the upstream flow regulating valve, straight pipe length shall not be less than 5 dn before table, the table after the straight pipe length should not be less than 3 dn, and flange connection type (low pressure) sealing washer must not into the pipe.Joint quickly mounted in welding entered should be welded the watch case and display again.

3, new pipe should use the bypass pipe water in front of the flowmeter using the stones within the pipeline, sediment, linen, silk, and rinse clean welding slag.If medium contains many impurities in use, the filter must be installed upstream, in order to avoid impurity blunt bad electrode, filter water area should be greater than the nominal diameter of 1.5 times the cross-sectional area.

4, when the liquid crystal display obvious value becomes weak or supply voltage is lower than 2.6 V, should be timely transform four sections of high-performance alkaline batteries.Replacement should open the display inside the back cover and the battery case cover plate, remove the battery and circuit for 1 to 2 minutes more electricity, after all is put on positive and negative mark again quickly put on the new battery, it can make the stored data display correctly.5, display signal output terminal of the mouth can be flow signal transmission or with microcomputer system connected to the Internet.Wiring, unscrew the connection mouth M20 x 1.5 hexagon nut and rubber seal from the wiring inside the mouth into the press mark solid wiring terminals, and the hexagonal nut, put on the back cover.If it is a three wire system output, to 6 mm in three core sheathed shielded wire will each of the three core line in power supply, signal, grounded on the three terminal;If it is a two wire output (output) for the switch signal, to 6 mm in two core sheathed shielded wire will be 2 wire core, respectively in the signal, grounding on the two terminals.

Seven, selection considerations:

1, the liquid to be tested must be able to conduct electricity, cannot be used for measuring gas, oil and organic solvent such as non conductive medium flow.

2, should not contain a large number of measured medium bubble, otherwise it will affect the measurement accuracy.

3, the current body should be in the full range of flow meters between 20-80%, in order to obtain high measurement precision.

4, should according to the corrosion resistance and temperature of the measured medium, select the appropriate electrode materials.

5, according to the installation of flowmeter choose different azimuth display, in order to observe.

Eight, parameter table:

Nine, selection of code:

Ten, design selection and ordering information:

1, indicate the diameter of the magnetoelectric meter need, connecting method, flow range, pressure level, with length and the connection can be made according to user requirements.

2, if you need to remote the separation of transmission distance shall be indicated when ordering.

After-sales service commitment:

1, my company's products sold by flowmeter appeared quality problem within 12 months, responsible for free maintenance.

2, the warranty period, any quality problems such as the products of our company, my company is responsible for free repair or replacement.

3, the warranty period, such as user improper use, damaged products, my company is responsible for the maintenance, charge damage parts cost.

4, after the warranty period appear quality problem, my company is responsible for the maintenance, charge damage parts cost.

5, such as user need to my company site services, to users in the province I company service personnel to reach the site within 12 hours, fujian association of foreign languages and user reach the site within 48 hours.
