Characteristics and uses of vortex flowmeter
a: Features:â‘ The anti-vibration performance is particularly good, no zero drift, and high reliability. Through a large number of waveform analysis and spectrum analysis of the vortex flowmeter for a long time, coupled with the best probe shape, wall thickness, height, probe rod diameter and matching piezoelectric crystal, it is processed by an advanced CNC lathe. , To ensure the technical parameters such as the coaxiality and smoothness of the processing, and to cooperate with special processing, so as to overcome the common problem of the inherent self-oscillation frequency of the vortex flowmeter on the signal.
â‘¡The sensor of the intelligent vortex flowmeter is very versatile, so that the sensor has good interchangeability. The surface of the sensor and the vortex generator are processed by advanced numerical control equipment to ensure the processing accuracy, so that the parts (especially the vortex (Generator) is versatile, so that it will not affect the repeatability and accuracy of the sensor due to the replacement of parts; it can generate a strong and stable vortex signal.
â‘¢Simple and firm structure, no moving parts, high reliability, easy to use and maintain.
â‘£The detection element is not in contact with the medium, the performance is stable, and the service life is long. The sensor is installed separately from the vortex generator and the high temperature resistant piezoelectric crystal is sealed in the detection probe, and does not contact the measured medium, so the vortex flowmeter It has the characteristics of simple structure, good versatility and high stability.
⑤ Output pulse signal or analog signal proportional to flow rate, no zero drift, high precision, easy to connect with computer
â‘¥Wide measurement range, range ratio up to 1:10
⑦The vortex flowmeter does not need to compensate when measuring the volume flow. The signal output by the vortex is actually linear with the flow rate, that is, proportional to the volume flow. The purpose of pressure and temperature compensation is to obtain the density of the fluid and multiply it by the volume flow to obtain the mass flow. If the volume flow of the measured gas does not need to be compensated.
⑧ Small pressure loss. Use the DN50 vortex flowmeter to measure the flow of combustible gas. If the maximum flow in the pipeline Qmax = 200m3 / h, the pressure loss of the sensor is: â–³ P = 1.08 × 10-6 Ïv2 (kPa) = 0.605 KPa
⑨ Within a certain Reynolds number range, the flow characteristics are not affected by fluid pressure, temperature, viscosity, density, composition, but only related to the shape and size of the vortex generator.
â‘©Wide range of application, steam, gas, liquid flow can be measured.
b: Purpose:
This flowmeter can be widely used in large, medium and small pipes for water supply and drainage, industrial circulation, sewage treatment, oil and chemical reagents, compressed air, saturated and superheated steam, natural gas and various media flow measurement.
2-2.5 Ton Electric Pallet Truck
Zowell Electric Pallet Truck with 2000~2500kg load capacity is a material handling equipment mainly used in the transfer of materials in pallet inside and outside the production line and warehouse. The pallet truck is only used for plane transportation for no lifting mast. Although the pallet truck cannot lift the goods, but the purchase and maintenance costs are quite lower than other forklifts.
Zowell XP electric pallet trucks are equipped with AC drive motor and multi-functional handle, emergency switch, dual balance wheel as well as side loading battery for safety, efficiency and less fatigue in operation. Buffered pedal also extends the flexibility for various scenarios.
Detail features
1. Multifunctional handle
The multifunctional handle is imported from Germany. The operators can control
the moving speed easily through the use of the handle, which is equipped with
an emergency reverse button. This effectively protects the operator against
injury in the event of an accident. The handle can achieve braking in both vertical
horizontal positions, thus improving the tugger safety.
2. Safety protection
The soft PU armrest features a superior resistance to compression and impact,
thus reducing indirect hits and injury during stacker movement. This can
provide safety protection as well as comfort for the operators.
3. Safety switch
The power can be rapidly cut off in an emergency to ensure safety.
4. Buffered pedal
The foldable pedal saves space when the stacker is not in use. It features an
excellent shock absorption function, providing comfort for the operators, and
reduce working fatigue.
5. Side loading and unloading of storage battery
Side loading and unloading of storage battery makes maintenance and changing
easy. Users can select among different brands, including FAMM, GS, HOPPECKE,
and Trojan.
6. Dual balance wheel device
This device has a high passing ability because the running is stable.
7. AC drive
The maintenance free AC drive motor has no carbon brush, no contacts, a large
torque and large output power. It uses a rear axle drive, providing perfect
power and gradeability.
8. Lifting height limit
The lifting height can be precisely controlled to reduce energy waste.
9. Multifunctional meter
A multifunctional meter can display integrated electricity quantity, working time
and failure codes. The operators can know the running condition of the stacker
via the meter.
10. High power pump station
The 2.2kw high power pump station can provide a strong power for transporting
goods. The noise is low as well. The whole truck noise is lower than 70 dB.
