Description:

Productoverview:

ZW-LL-B series Stainless steel flowmeter (meter) is referred to as a volume flow measuring instrument, measuring part and the shell is made of stainless steel, with strong corrosion resistance, can be used for the flow measurement of crude oil moisture corrosion or other corrosive media. This scene shows the cumulative flow and flow meter can be equipped with remote output interface, the other with the photoelectric converter output electric pulse signal or analog signal, matched with a flow meter for remote measurement, display and control.

The utility model is characterized in that a metering chamber in the meter casing, the metering chamber has a pair or two pairs of tangent waist wheel rotation. In the outside of the casing and the coaxial flowmeter both search round a set of transmission gears meshing with each other, they make a waist wheel can be linked with each other.

Second, working principle:

ZW-LL-B series stainless steel turbine flowmeter is measured when the fluid flows through the metering chamber, in the import and export of the formation of differential pressure flowmeter, this pressure waist wheel driven by rotation. At the same time through fixed at the waist on the axle of the driving gear, the two round of continuous rotation of the waist. With the rotation of the waist wheel, the metering chamber is discharged continuously through the liquid flowmeter. The amount of each liquid flow through the metering chamber volume is four times, the sealing mechanism through the coupling, reducer, reducer rotating number is transferred to the counter, the counter is indicating liquid instantaneous flow and cumulative flow. Install the transmitter in the counter mechanism that the sender of the waist belt. With the display meter or computer system can realize remote (quantitative, cumulative and instantaneous automatic measurement and control function). Use display instrument Classification Manual see.

Third, application:

ZW-LL-B series stainless steel flowmeter is mainly composed of a metering chamber, coupling and sealing three parts counter. Widely used in petroleum, chemical, electric power, metallurgy, transportation, food processing, medicine, defense, trade and other departments accurate measurement of oil and oil products, chemical solution and other fluid.

Fourth, the main features:

1, high measurement accuracy, the basic error is generally up to plus or minus 0.2% to the positive and negative 0.5%, special requirements up to plus or minus 0.1%, flow characteristics generally not affected by the flow state, nor by the Reynolds number size limit.

2, can be used for high viscosity liquid flow measurement

3, a wide range of measurement, the typical flow range of 5:1 to 10:1

4, the cumulative amount of fluid type wheel counter, without external energy, the use of instant noodles counter cumulative flow double display, one of which can be reset to zero, the convenience of users in the case of continuous measurement.

5, the measurement between components without contact, no wear, long service life.

6, large caliber flowmeter and the rotor, reduce running noise and vibration meter.

Fifth, technical parameters:

1, allow the basic error: + 0.1%, + 0.2%, + 0.5%;

2, the nominal diameter of DN (mm): 15~300;

3, nominal pressure PN (M.Pa): cast iron, stainless steel (A) (P) 1, 1.6, 2.5, 4, 6.3; 2.5, 4 cast steel (E), 6.3, 9.6;

4, the measured liquid temperature:

A. low temperature: -40 ~ +60 c;

B. at room temperature -10 to +80 DEG c;

The temperature of C. -10 to +200 DEG c;

D. high temperature -10 to +300 DEG c;

5, the measured liquid viscosity (mPa.s): 0.3 ~ 50000;

6, pipe connection: GB/T9118-2000 (Chinese; NIST (American Standard) standard); BSPT (BSP): NPT (American pipe thread);

7, on-site display: L (cumulative flow) of 9999999.9 L (single flow); 9999999.9 L (transient flow);

8, output signals: pulse signal, 4 ~ 20mA, 4 ~ 1-5V, 20mA +HART, MODBUS RS232, RS485 protocol support communication (Ren Xuan);

9, explosion-proof grade: EXiaIIBT5EXiaIICT5 protection grade: IP65.

Application of measurement of flowmeter, 6:

ZW-LL, can be used for pure crude oil, heavy oil flow measurement of high viscosity liquid;

ZW-LL-D can be used to prevent sand sand flow measurement of crude oil, heavy oil and other high viscosity fluid;

ZW-LL-B stainless steel is the contact with the medium flow meter stainless steel material manufacturing, has strong corrosion resistance, can be used for flow measurement of corrosive liquid, especially for the chemical industry;

ZW-LY-C light oil type is especially suitable for light oil, diesel oil flow measurement of low viscosity fluid.

Seven, installation and use:

1, flow meter should be installed before the filter, the meter with the direction of arrow.

2, when the measured liquid containing gas, flow meter should be installed before the gas separator.

3, whether the pipeline is vertical or horizontal installation, but the waist wheel flowmeter installation into a horizontal position (i.e. dial should be perpendicular to the ground).

4, the correct installation of flowmeter in the case, if it is not easy to see the readings, the counter rotating 180 degrees or 90 degrees can be.

5, the throttle valve should be installed in the meter inlet opening and closing valve is installed at the outlet, the use of open or close the valve to start slowly, do not suddenly open valve.

6, prohibited the use of steam flowmeter by line sweep.

7, in the continuous use of departments, need to add a bypass pipeline flowmeter.

Before the installation of 8, flow meter, pipeline flushing, flushing the pipe (alternative meter position) prevent the welding slag and other debris into the meter.

9, check the water meter is composed of cast iron, cast steel.

10, when using the size of the flow meter shall not exceed the technical requirements. The flowmeter work on Zui flow 70~80% was better.

11, if the measured liquid is corrosive, need to use stainless steel flowmeter, if corrosive, need to use 0Crl8Ni12MO2Ti material flow meter.

Eight, installation notes:

1, before installation shall not open the inlet flow, the outlet seal two;

2, when the pipe is installed on the device more, should be put on after the installation of flow meter;

3, where conditions permit, the pipeline must be high pressure purge before installation;

4, the installation should at the interface of iron pins, careful removal of burr;

In front of the 5 meter must be installed, filter, filter media measurement; measurement of liquid, if containing gas, optional getter device flowmeter, ensure the measuring precision of flowmeter;

6, installation modes, horizontal vertical installation can be installed vertically progress under the lower upper is not affected, but the meter shall not be reversed, anti loaded, opposite directions, waist wheel reversal, because the rotation between different gap design will damage the waist wheel;

7, on the lower straight pipe section, but must set aside to install filtering device enough distance;

8, the waist wheel rotation by fluid pressure is the force of viscous medium, when the measurement is too high, affect the measuring precision of flowmeter;

To avoid the above points, the measurement precision can achieve better flowmeter.
