Product Details
Description:

Productoverview:

ZW-LZ series sanitary type metal tube rotameter with local display and intelligent remote type, with a pointer to display the instant / cumulative flow of liquid crystal display, upper and lower limit alarm output, pulse output, batch control standard, two-wire 4-20mA current output and other forms, for the user to provide a very broad space, in addition to the the instrument adopts the advanced micro processing chip and high quality industrial central components, ensure the flow in all kinds of applications with good performance.

Two, work principle:

ZW-LZ series sanitary type metal tube rotameter is the medium to be measured through a conical measuring tube float from upper and lower ends of the differential pressure generated form the upward force, when the float was immersed in a fluid on the lift is greater than the weight of the float, the float will rise, annulus area increases, the annulus fluid velocity decreased immediately float the lower end of the differential pressure is reduced, to float upward force also decreases with, until the lift is equal to the weight of the float when immersed in a fluid, the float will stabilize at a certain height. The float position that corresponds to the size of the measured medium flow. A built-in magnet, the float with the medium moves up and down, with the movement of the float magnetic field changes.

A, for in situ, by rotary magnetic float and the local indicator in the inner magnetic coupling, rotate, and drives the pointer, through the dial indicates the size of the flow.

B, the intelligent, by a solid state magnetic sensor intelligent indicator in the magnetic field will change into electrical signal output by A/D transform, D/A microprocessor, LCD liquid crystal display to show the size and cumulative flow flow.

Three, application:

ZW-LZ series sanitary type metal tube rotameter is suitable for small flow, low Reynolds number of medium flow measurement is widely used in food, chemical, petroleum, metallurgy, electric power, environmental protection, medicine and light industry and other departments of the liquid flow measurement and automatic control.

Four, main features:

1, suitable for small diameter and low flow velocity medium measurement;

23, intrinsically safe explosion proof mark: ia II CT6 flameproof D II BT4.

Six, the type of flow meter:

1, the metal tube flowmeter will 5 types of products according to the fluid into the entrance and exit direction: vertical type, horizontal type (including the level T, level of spring type), into the side of the bottom and side into the side, side in the type, and each type and standard type, high temperature type, jacket type etc..

2, the level of the installation type meter when the diameter is less than DN50 (inclusive), using T structure, when more than DN50, the spring structure.

3, specifications: standard type flowmeter is connected with GB/T9119-2000 standard flange, flange standard can be made according to customer demand; also can be used threaded connection, clamp connections.

Magnetic filter:

If there is a ferromagnetic particle medium, magnetic filter installed in the entrance before the flowmeter.

Seven, conversion indicator:

The converter is actually the height conversion taper pipe float into the corresponding volume scale. From the output signal: local display and remote signal output type:

1, local display type: by in situ indicator in the follow-up magnetic float and the inner magnetic coupling, and rotate, and the electric pointer by dial indicating the flow

2, intelligent remote type, by the intelligent indicator in the follow-up magnetic float and the inner magnetic coupling, rotate, and drives the magnet and the sensing pointer through a magnetic sensor magnetic field change into electrical signals by A/D conversion, digital filter, D/ microprocessor, A output, LCD liquid crystal display, to show the instantaneous flow and cumulative flow rate.

Eight, product maintenance:

1, in the process of long-term use, the pipeline inevitably there will be ferromagnetic impurity adsorption on the float, it will float stuck or affect the measurement accuracy, from time to time to clean the sensor float; if the installation of magnetic filters should be cleaned regularly.

2, the instrument indicator with electronic components, instrument wiring or demolition of housing, to housing screws, must ensure sealing, prevent impurities, or other material into the water, and also to ensure reliable earthing of the meter casing.

3, the instrument is installed, in use, should pay attention to:

When the valve is opened to avoid the formation of pressure shock makes the float slamming limiting device, causing damage to the instrument, slowly open the valve!

The measurement of gas meter is equipped with gas damper, Zui to decrease the float concussion; to ensure the stability of the float, a throttle valve can be installed in the instrument export.

4, for the remote type instrument, we must first ensure that the instrument wiring correctly, keeps power; for dangerous situations, must choose the explosion-proof, and the installation and use of proof required by the.

Nine, matters needing attention:

1, in the installation before the first pipe flowmeter, dirt, impurities such as welding blowing clean, if the liquid contained solid impurities, should the corresponding filter is installed between the valve and the straight pipe.

2, shielding and grounding system: in order to ensure the ideal electromagnetic compatibility, shielding and grounding is very important, especially the bus cable, cable as far as possible to make continuous shielding.

3, the safety zone, according to the requirements of conventional cable grounding as much as possible.

4, in dangerous places, to ensure that the whole range of bus safe places and dangerous enough, all the potential, in this case, multiple ground is very superior.
