The OLTF series liquid turbine flowmeter measures flow by detecting the rotation of a turbine placed in the flow path. As liquid passes through, it spins the turbine, generating a pulse signal. Advantages include high accuracy, wide flow range, low pressure drop, and suitability for various liquid applications.
The OLTF series turbine flowmeter is designed based on the principle of torque balance and is a speed type flow meter. It has the characteristics of simple structure, light weight, high precision, good reproducibility, no internal adjustment parts, sensitive response, and easy installation, maintenance and use.
Using high-performance microprocessor technology, the whole instrument has powerful functions and high computing accuracy.
The flowmeter adopts a laminated structure, which is easy to disassemble and maintain. There is no mechanical and electrical adjustment and no need for debugging.
LCD can display instantaneous flow and cumulative flow on-site, and the readings are intuitive and clear.
Output pulse signal or 4~20mA flow signal. RS485 port for Modbus communication and optional HART communication.
Press the buttons to set the instrument parameters, and the operation is simple and convenient.
5-segment coefficient correction to ensure wide range measurement accuracy.
Can be used in explosive environments.
The OLTF series turbine flowmeter is mainly used for measuring, transmitting and on-site display of the flow and total volume of liquids in closed industrial pipelines. It can also be used as a standard instrument to calibrate other flow meters and is widely used in petroleum, chemical industry, aviation fuel, metallurgy and scientific research departments.
