The insertion flow sensor is essentially an electromagnetic flow sensor.
The excitation coil and electrodes are assembled into a rod shape and inserted into the opening of the pipe to be tested. Factors such as the measured flow rate and the converter's preset pipe area are multiplied by the hydrochloric acid to obtain the flow rate. In addition to single point flow velocity, there is also runoff velocity. This instrument is suitable for large pipelines because it measures local flow velocity to calculate fluid flow. The measurement accuracy is lower than that of short pipe types. It is usually only used for process control and is not suitable for trade accounting measurement, but the price is relatively cheap.
Classification by use
In industries such as metallurgy, petrochemicals, papermaking, printing and dyeing, textiles, water supply, and sewage treatment, large-diameter flange connections are generally used; medicine, biology, fine chemicals, etc. Small-diameter, small-diameter instruments, integrated fixture connections or threaded connections are commonly used in the industry.
Explosion-proof and explosion-proof electromagnetic flow meters are used in places with flammable atmospheres. Since most electromagnetic flowmeters have a large amount of current energy, they are usually designed as explosion-proof, sand-filled, cast-sealed and air-tight types. However, some electromagnetic flowmeters now have greatly reduced magnetic power, and there is a basic safety type, which was formerly known as the safety spark type. The flow sensor part and conversion part are conditional and both are installed in hazardous areas.
Hygienic industries such as cheese, food, medicine, and biochemistry require regular steam sterilization. Sensors should be easy to disassemble and clean. Pipe connection parts require quick loading and unloading of hygienic structures. Materials in contact with liquids should be non-toxic and non-toxic. Harmful. Sanitary electromagnetic flow meters are developed to meet the above requirements.
The inspection well installed underground is submersible and can withstand short-term water intrusion, which is equivalent to the shell protection grade IP67 or NEMA6; it is also equivalent to the protection grade IP68 and can withstand long-term diving.
The submersible type is used to measure natural water flow in open channels or non-fully piped culverts, such as industrial drainage and drainage. The sensor is installed under the open channel interception baffle and soaked in water for a long time. Used to install multiple split flow models with the same shape as the sensor to expand the flow rate when the flow rate is high.
