Application and installation of Verabar flow meter
Verabar flow meter can be used for underground pipeline industrial water, filter water, circulating water and other media flow measurement, due to the sediment and other miscellaneous mass, medium temperature is not very high, generally at room temperature, pressure does not exceed 1.6mpa, and production process pipeline production opportunities are few, basically do not have the opportunity to stop the pipeline emptyout. When selecting, its plan is to use the on-line installation type Verabar. These probes are easy to be pulled out and cleaned at any time.Of course, if the user's dust removal effect is good, we also recommend non-online installation with back blow device, can cope with most cases.However, to pull out for maintenance, it can only be carried out when out of production, unless a valve or threaded bolt is specially fitted to block the welding joint.
Installation of Verabar flowmeter:
On horizontal pipeline installation, when the medium is air and gas, power and should be installed in any position above 160 °, so can not guarantee in the gas liquid into the guide tube, the transmitter must be installed in a higher power and position as far as possible, open for drainage operation table.For liquid and steam is 160 ° in the lower part of any position, for liquid can make any bubbles into the pipe, when conditions permit can only be placed in the upper, the open table for exhaust operation (underground pipes basically the same, in the case of underground pipeline in the mud, suggested probes should be installed vertically, to ensure that the probe is similar on both sides of the medium flows, that are less likely to take pressure hole plugging), allows for steam condensation water enters the guide pipe into the condensing pipeline, transmitter power must be installed as far as possible below the position.In vertical pipe runs for installation, can be installed in vertical pipe runs around the 360 ° any location (meet straight pipe section), pay attention to the correction after installed probe direction, the direction of the fluid on the probe "- >" keep within 3 ° with pipe flow direction.
Due to the calculation of flow meter power differential pressure is small, generally not to drain, if long time blow down will break the probe of high pressure hole pressure balance, will lead to the row of the wall, still can make low pressure hole jam, low flow indicator after open the table again, so normally in the instrument maintenance system checks and only one meter to zero, especially important for measuring instrument can take on a regular basis to clean power and the probe, once/month, for example, when cleaning inspection probe and the positive and negative pressure hole appearance dredge situation,At the same time, in order to ensure the accurate measurement of the lower differential pressure, it is necessary to ensure that the static sealing points of the measurement system do not leak when restoring the installation.
