Burkert flow switch Burkert 8025 flow meter 418778 418779 418762 Burkert insertion turbine flow meter or batch controller, Burkert flow meter 8025 model 418778 418779 418762 turbine flow transmitter for continuous flow measurement and batch control is specifically designed for neutral and slightly corrosive liquids that do not contain solids.

The performance aspects of Burkert flow meters mainly include: measuring flow (instantaneous flow) or total flow (cumulative flow); accuracy requirements; repeatability; linearity; flow range and rangeability; pressure loss; output signal characteristics and flow meter response time, etc.

• Measuring flow or total flow Burkert flow meter flow measurement includes two types, namely instantaneous flow and cumulative flow. For example, for crude oil in distribution station pipelines, which are trade transfers or for continuous proportioning production or process control of production processes, total flow needs to be measured, and instantaneous flow is occasionally observed. In some workplaces, instantaneous flow measurement is required for flow control. Therefore, the selection should be based on the needs of on-site measurement. Some Burkert flow meters, such as volumetric flow meters and turbine flow meters, measure the total volume directly by mechanical counting or pulse frequency output. They have high accuracy and are suitable for measuring total volume. If equipped with a corresponding signaling device, they can also output flow rate. Electromagnetic flow meters and ultrasonic flow meters derive flow rate by measuring fluid velocity. They have fast response and are suitable for process control. If equipped with an integration function, they can also obtain the total volume.
• Accuracy The accuracy class of Burkert flow meters is specified within a certain flow range. If used under specific conditions or within a relatively narrow flow range, such as only varying within a very small range, its measurement accuracy will be higher than the specified accuracy class. For example, if a turbine flow meter is used to measure oil for barrel distribution, and the valve is fully open, the flow rate is basically constant, and its accuracy may increase from 0.5 class to 0.25 class.

• Burkert flow transmitters operate based on the principle of vibration, and in their operation, they utilize electromagnetic technology for vibration excitation, torsion detection, and signal processing. Therefore, the installation location of the Burkert flow transmitter should not be near large vibration sources, nor should it be installed near equipment that generates strong magnetic fields, such as transformers or motors, to prevent external interference from affecting its normal operation.
• The installation of the Burkert flow transmitter does not require a straight pipe section, but stress should be avoided when the sensor and the pipeline. If there is a deviation in the concentricity between the sensor and the pipeline centerline during the installation of the Burkert flow transmitter, stress will be generated in the vibrating tube. fluctuations, and affecting measurement accuracy [3, 4]. If the concentricity deviation between the pipeline and the sensor is too large, it may be impossible to adjust the zero point. Therefore, reinforcement measures should be taken to stabilize the pipeline near the instrument. A flexible connection should be used as much as possible when installing the flow sensor, and the flange connection bolts should be tightened evenly and symmetrically. To reduce the influence of residual stress, the flow sensor should be zero-point calibrated after installation. To facilitate the installation and zeroing of the Burkert flow transmitter, shut-off valves should be installed at the front and rear ends of the Burkert flow transmitter.
• The connecting cable between the sensor and the transmitter should use the manufacturer's cable;
• the transmitter receives low-level signals, so the cable should not be too long. When installing the transmitter, ensure the partition separating the intrinsically safe sensor cable from the power and output cables is properly in place;
• ensure the sensor junction box and transmitter housing are sealed to prevent short circuits that could lead to measurement errors or flow meter malfunctions.
• Select different sensor installation orientations based on the fluid properties. Always keep the fluid in the sensor flow tube full. For gas feed measurement, the U-tube of the Burkert flow transmitter should face upwards to prevent condensation buildup in the measuring tube; for the LUX type, adjust the potentiometer located next to the display module;
• for the LUY type, adjust the potentiometer in the temperature and pressure circuit on the lower left of the main board (only one). Rotating the potentiometer clockwise decreases the displayed pressure value. The Burkert flow transmitter can measure the flow rate of dirty media, corrosive media, and suspended liquid-solid two-phase flows. Since the only flow components inside the measuring tube of the instrument are the lining and electrodes, which come into contact with the fluid being measured, their materials can be selected based on the properties of the fluid. For example, using polytetrafluoroethylene (PTFE) or polytetrafluoroethylene (PTFE) as the lining allows for the measurement of various corrosive media such as acids, alkalis, and salts;
• using wear-resistant rubber as the lining is particularly suitable for measuring liquid-solid two-phase flows such as slurries and cement slurries containing solid particles and exhibiting significant abrasion, as well as various fibrous liquids and suspensions such as pulp. Features of Burkert flow transmitters and Burkert flow switches: ① The internal circuitry of Burkert flow transmitters uses surface mount technology, resulting in a compact structure and high reliability. ② Burkert flow transmitters can operate with either internal or external power supplies depending on site requirements, resulting in low overall power consumption. ③ Burkert flow transmitters have a password setting function.
