Why Choose Feejoy's Magnetostrictive Level Transmitter?

Feejoy Technology's magnetostrictive liquid level gauge can measure the oil tank's liquid level and temperature, and can also measure the oil tank's leakage. The leak detection accuracy reaches 0.375 liters/hour, which can meet the needs of different users, to achieve a higher price-performance ratio.

What parts is magnetostrictive liquid level gauge composed of?

Detection rod, circuit unit and float. During the measurement, the circuit unit generates a current pulse, which is transmitted down the magnetostrictive line and generates a ring-shaped magnetic field.

What advantages does magnetostrictive level transmitter have when measuring the oil tank liquid level?

Strong reliability: Since the magnetostrictive liquid level gauge adopts the principle of the waveguide, there is no mechanical movable part, so there is no friction and no wear. The entire converter is enclosed in a stainless steel tube and is not in contact with the measurement medium. The sensor works reliably and has a long life. High precision: Because the magnetostrictive liquid level gauge works with waveguide pulses, the measured displacement is determined by measuring the time of the start pulse and the end pulse during the work, so the measurement accuracy is high, and the resolution is better than 0.01% FS, which Accuracy that is difficult to achieve with other sensors. Good safety: The magnetostrictive liquid level gauge has high explosion-proof performance, intrinsically safe explosion-proof, and is safe to use, especially suitable for the measurement of chemical raw materials and flammable liquids. It is not necessary to open the tank lid during measurement to avoid the unsafeness of manual measurement. The magnetostrictive liquid level gauge is easy to install and maintain: the magnetostrictive liquid level gauge is generally installed through the existing nozzle on the top of the tank and is particularly suitable for the installation of underground storage tanks and operational storage tanks. The process does not affect normal production. Facilitate system automation work: The secondary instrument of the magnetostrictive liquid level gauge adopts standard output signals, which is convenient for the computer to process the signal, and it is easy to realize networked work and improve the automation degree of the entire measurement system.

Working Process of Turbine Flow Meter

Flow meter with turbine measurement first converts the flow rate to the speed of the turbine, and then converts the speed into an electrical signal proportional to the flow. This kind of flowmeter is used to detect instantaneous flow and total integrated flow. Its output signal is frequency, which is easy to digitize. And the working process needs to ensure the turbine meter accuracy.

The induction coil and the permanent magnet are fixed on the housing together. When the ferromagnetic turbine blade passes the magnet, the magnetic resistance of the magnetic circuit changes, thereby generating an induction signal. The signal is amplified and shaped by the amplifier and sent to a counter or frequency meter to display the total integrated flow.

At the same time, the pulse frequency undergoes frequency-voltage conversion to indicate the instantaneous flow. The speed of the impeller is proportional to the flow rate, and the number of revolutions of the impeller is proportional to the total amount of flow.

The output of the turbine flowmeter is a frequency-modulated signal, which not only improves the anti-interference of the detection circuit, but also simplifies the flow detection system. Its range ratio can reach 10: 1, and the accuracy is within ± 0.2%. The time constant of the turbine flowmeter with small inertia and small size can reach 0.01 seconds.

Development of Turbine Flow Meter

Turbine flowmeters in Europe and the United States are the second legal natural gas flowmeters after the orifice plate flowmeters. They have been developed into multi-species, full-range, multi-specification, mass-production natural gas flow meter.

The standard specifications are also very complete, but there are also shortcomings: the cleanliness of the measurement medium is high, and the use period is limited. However, according to foreign usage departments: 240 flowmeters that have been used for 8 to 15 years have been periodically verified and found that the accuracy deviation of the instrument is still within the specified range.

In addition, a high-efficiency rectifier is coupled with the turbine flow sensor to form a gas turbine flow meter with an integrated structure. Only 2D straight pipe length is required when the upstream side flow block is an elbow or a half-open stop valve. It is a very outstanding feature for the narrow installation space for urban use.
