BYM-XX wedge flow meter is a V type throttling element for flow rate measurement of flow meter,It's sleek angle downward, that conducive to liquid contain with particles suspended or viscous fluid pass through smoothly, avoid generates stagnation in the upstream of throttling element wedge flowmeter can be used for viscous liquid flow measurement,the viscosity can be up to 500mPaS, which can use for the slurry, pulp, sediment, heavy oil, crude oil, waste residue suspension containing solids low Reynolds number and liquid medium flow measurement, it also can be used for gas, steam flow of a medium.
The BYM-XX series products are used in a variety of gas, especially suitable for dirty gas and natural gas flow measurement.
1, Application and features:
1, the" V" type throttling device can eliminate the residuce area, to
prevent stagnation phenomenon occure. in the system
2.with wide range of application for Reynolds number, can stay with
square relation between differential pressure and flow rate at the Reynolds number of 500
3. the differential pressure transmitter can output 4 to20mA, suitable for all kind of instrument .
4. easy to installment and maintenance.
5.high measuring precision, flow calibration uncertainty:± 0.5%~± 0.2% ( water calibration oil calibration)
6, long-term stability,
7.a table seperately. can extended range through replacing the wedge( intermediate0
8 Diverse types
general type; measure range ratio 1:3, flow coefficient of non linear 0.5%~±0.2%.
High performance type: flow calibration uncertainty of + 0.5% to + 0.2%. at the measure range ratio 1:10
Material: stainless steel, carbon steel.
the installation site:
BYM-XX series Wedge Flowmeter can operate normal even under the harsh condition, but for the sake of long-term safe and stable use, please note the following points: when in the installation,
The shock and vibration at installation site, BYM-XX series Wedge Flowmeter is design to withstand the shock and vibration. But should be notice shock or vibration
in the installation
The environment and air condition of the installation site;
BYM-XX series Wedge Flowmeter should be avoided in corrosive environment as possible, if used in the corrosive environment, should have good ventilation and avoid the corrosive gas or liquid to immersed instrument.
The environmental temperature conditions of the instalaltion site:
Please try to avoid the flow meter being installed in the place which ambient temperature changes so often, if the installation position is directly affected by thermal radiation or exposure in the daily Sai rain, should adopt waterproof, heat radiation and ventilation measures.
the Wedge Flowmeter can install and used in horizontal or vertical piping, when the sensor is in vertical pipeline installation, the fluid flows from bottom to top, when liquid is measured, attention should be paid to the differential pressure transmitter can conveniently remove air bubbles, so as not to cause instrument drift. sensors shall install and use at the same nominal diameter pipeline pipeline inner wall should be smooth, clean, no attachment, the sensor should be prepared on the downstream side straight, straight section
The environmental temperature conditions of the instalaltion site:
Please try to avoid the flow meter being installed in the place which ambient temperature changes so often, if the installation position is directly affected by thermal radiation or exposure in the daily Sai rain, should adopt waterproof, heat radiation and ventilation measures.
