Overview
The intrinsically safe high-pressure online flowmeter for mining, impeller flow sensor, and high-pressure flowmeter are intelligent flow measurement and control products that integrate flow measurement, output, and control. This product consists of an impeller body and electronic structure. The output pulse signal is processed by a high-precision, high-speed, and low latency microprocessor. By calibrating and calculating the flow rate, flow rate, pressure, pipe diameter, and pulse relationship, the generated flow rate can be calculated based on the number of pulses. The processed signal is remotely monitored and controlled to measure and control the system flow rate. Flexible to use, easy to operate, easy to debug, safe and reliable.
Product Details
Mining intrinsic safety high voltage online flowmeter impeller flow sensorIt is an intelligent flow measurement and control product that integrates flow measurement, output, and control. This product consists of an impeller body and electronic structure. The output pulse signal is processed by a high-precision, high-speed, and low latency microprocessor. By calibrating and calculating the flow rate, flow rate, pressure, pipe diameter, and pulse relationship, the generated flow rate can be calculated based on the number of pulses. The processed signal is remotely monitored and controlled to measure and control the system flow rate. Flexible to use, easy to operate, easy to debug, safe and reliable. There are no particularly strict requirements for the installation direction of the intrinsically safe high-pressure flowmeter impeller flow sensor stainless steel pressure resistant high-pressure flowmeter used in Chaohui Mining. Generally, it can be installed horizontally, vertically, or tilted without any restrictions. However, it must be reminded that in order to ensure that the pipeline is filled with the measured medium, that is, in a "full pipe" state, it is recommended to install it vertically and flow from bottom to top, especially for liquid-solid two-phase fluids, which must be installed vertically. If only horizontal installation is allowed on site.
It is necessary to ensure that the two electrodes are in the same horizontal plane, and the axis of the electrodes must be approximately horizontal, because the electrode at the bottom is easily covered by sediment, and the top electrode is easily wiped by occasional bubbles in the liquid, covering the surface of the electrode and causing fluctuations in the output signal.
7.1.1 Mining intrinsically safe high-pressure online flowmeter impeller flow sensor. The upstream of the high-pressure flowmeter is generally a 10DN straight pipe section, and the downstream has a 5DN straight pipe section. At least a 5DN straight pipe section is required, and the downstream has at least a 3DN straight pipe section. In order to facilitate installation and disassembly, pipeline expansion joints can be installed;
7.1.2 The flow direction of the fluid is consistent with the direction indicated by the arrow on the flowmeter housing;
7.1.3 High pressure flow meters should be kept as far away as possible from pumps, valves, and other equipment to avoid interference with measurement;
Flow meters should be kept as far away as possible from sources of interference such as radio frequency, strong magnetic fields, and strong vibrations;
7.1.5 If there is vibration in the measuring pipeline, there should be fixed supports on both sides of the flowmeter;
7.1.6 In order to facilitate the cleaning and maintenance of the flowmeter in the future, a bypass pipeline should be installed and a straight pipe section of 5DN in front and 3DN behind the flowmeter should be ensured;
7.1.7 To avoid signal interference, signal cables must be separately threaded in grounded protective metal tubes, and signal and power cables cannot be mixed in the same metal tube.
