Vortex flowmeter installation considerations

I. Introduction:
Vortex flowmeter is based on Karmen vortex street principle research and production, mainly used for industrial pipeline fluid flow measurement, such as gas, liquid, steam and other media. It is characterized by low pressure loss, large measuring range, high accuracy, and almost no influence of parameters such as fluid density, pressure, temperature, and viscosity when measuring volume flow. No moving mechanical parts, so high reliability and low maintenance. Instrument parameters can be stable over a long period of time. The vortex flowmeter uses a piezo-electric stress sensor, which has high reliability and can work in the operating temperature range of -20°C to +250°C. There are analog standard signals and digital pulse signals output. It is easy to use with digital systems such as computers. It is a relatively advanced and ideal measuring instrument.
Second, the requirements:
1. Requirements for the external environment The vortex flowmeter should be installed in places where the temperature changes greatly and the heat radiation received from the equipment. If it is necessary to install the vortex flowmeter, measures must be taken to prevent heat and ventilation.
3. The sensor should not be installed in an environment containing corrosive gas. If it must be installed, there must be ventilation measures.
4, the sensor is best installed indoors, must be installed outdoors, there must be moisture and sun protection measures, pay attention to whether the water will be 5, the cable into the amplifier box, wiring, the cable outside the electrical interface bent U type.
6. There must be plenty of space around the mounting sensor. There should be lights and electrical outlets for installation wiring and regular maintenance.
7, the sensor wiring location away from electrical noise, such as high-power transformers, motors and power supplies.
8. No transceiver can exist near the sensor installation point, otherwise high frequency noise will interfere with the normal use of the sensor.
Third, installation precautions
Vortex flowmeters are flowmeters that are sensitive to the effects of flowrate distortion, swirl flow, and pulsating flow within the tube. Therefore, when determining the installation location of the instrument, special attention must be paid to these influencing factors. During the installation, special attention should be paid to the distribution of the flow block and the length of the straight pipe section in the upstream of the instrument in accordance with the requirements of the manufacturer's instructions.
Most vortex flowmeters can be installed horizontally, vertically, or obliquely; a few (such as vibrating and photoelectric) must be installed horizontally. If the liquid is to be measured, it shall be ensured that the liquid to be measured is filled with pipes and the outlet of the instrument shall have a certain back pressure.

Garment Jacquard Fabric Machine

All the electronic jacquard machines under this garment jacquard fabric machine classification could weave various of dress,
jersey cloth,active-wear fabric,athletic wear fabric,workout fabric etc stably and sufficiently. These jacquard looms are applicable to various of textile weaving looms, such as rapier loom, air jet Loom, water jet loom, shuttle loom, Projectile Loom with any reed width. These digital jacquard machines are compatible with most brand of textile weaving machinery, just like ITEMA, SOMET, SMIT, PICANOL, DONIER, RIFA, TOYOTA, TSUDAKMOA etc.
