4mA～20mA Turbine Flow Meters For Water , Diesel , Gasoline
I. Overview
Turbine Flow Meters are specially designed for usage in water, diesel, gasoline and other fluid measurement and control systems. They operate according to the turbine principle, i.e. the speed of an impeller turning in the fluid flow is measured and converted into pulse or 4-20mA signals.
2. Turbine Flow Meters features:
■ The sensor is a hard alloy bearing thrust type, which not only guarantees accuracy, but also improves wear resistance;
■ The structure is simple, firm and easy to disassemble and assemble;
■ Wide measuring range, low flow rate at the lower limit;
■ Small pressure loss, good repeatability, high accuracy, and the impeller has anti-corrosion function;
■ Have high anti-electromagnetic interference and anti-vibration ability;
3. Working principle:
The fluid flows through the sensor housing. Because the blades of the impeller have a certain angle with the flow direction, the impulse of the fluid makes the blades have a rotational moment. After overcoming the friction torque and fluid resistance, the blades rotate. After the torque is balanced, the speed is stable. Under certain conditions, The speed is proportional to the flow rate. Because the blade is magnetically permeable, it is in the magnetic field of the signal detector (composed of permanent magnets and coils). The rotating blade cuts the magnetic lines of force, periodically changing the magnetic flux of the coil, so that both ends of the coil are changed. The electric pulse signal is induced, and the signal is amplified and reshaped by the amplifier to form a continuous rectangular pulse wave with a certain amplitude, which can be transmitted to the display instrument remotely to display the instantaneous flow rate and flow rate of the fluid. Cumulative amount. Within a certain flow range, the pulse frequency f is proportional to the instantaneous flow Q of the fluid flowing through the sensor, and the flow equation is: Q=3600×f/k
Where:
f——pulse frequency [Hz];
k——The meter coefficient of the sensor
Q——The instantaneous flow rate of fluid (under working condition) [m3/h];
3600-conversion factor;
The meter coefficient of each sensor is filled in the verification certificate by the manufacturer, and the k value is set in the matching display instrument to display the instantaneous flow and cumulative total;
4. Main technical performance:
■ Nominal diameter: DN4-DN200mm
■ Medium temperature: (-20-80)℃, (-20-120)℃, (-20-150)℃;
■ Environmental temperature: (-20-55)℃;
■ Accuracy grade: ±0.2%, ±0.5%, ±1%;
■ Output signal: voltage pulse, 4～20mA two-wire system;
■ Power supply: Sensor: +5V～+24VDC (external) Transmitter: +24VDC (external), flow meter: 3.0V lithium battery (built-in)
■ Display mode: on-site display, high-definition liquid crystal display simultaneously displays instantaneous flow (4 significant digits) and cumulative flow (8 significant digits, with clearing function). All valid data will be kept for 10 years after power failure.
