Pulse Output Intelligent Turbine Flowmeter
Solving Stable Flow Measurement for Clean Liquids
The PTF 125 Pulse Output Intelligent Turbine Flowmeter is designed for accurate and repeatable flow measurement of clean liquids in industrial process control applications.
Based on the torque balance principle, the turbine sensor converts fluid kinetic energy directly into rotational motion, producing a high-frequency pulse signal proportional to flow rate.
With a simple mechanical structure, fast dynamic response, and multiple signal output options, PTF 125 is widely used in water, oil, and light hydrocarbon measurement where stability and signal reliability are critical.

How does liquid viscosity affect turbine flow meter accuracy?
Turbine flow meters perform best with low to medium viscosity liquids. As viscosity increases, fluid drag on the impeller rises, which can reduce rotational speed and impact accuracy. For higher-viscosity media, calibration using the actual process fluid is recommended to maintain reliable measurement.
What is the relationship between pulse output and flow rate?
The pulse output frequency is directly proportional to the instantaneous flow rate. Each pulse represents a fixed volumetric increment defined by the meter factor (K-value), making pulse output ideal for batching, totalizing, and PLC-based control systems.
Can the pulse signal be transmitted over long distances?
Yes. Pulse output signals can typically be transmitted up to 300 meters, depending on wiring quality and electromagnetic environment. Proper grounding and shielded cables are recommended to ensure signal integrity in industrial installations.
Why is installation direction important for turbine flow meters?
Turbine flow meters must be installed in the correct flow direction and typically in horizontal pipelines. Incorrect orientation can affect impeller rotation stability, leading to inaccurate pulse output and reduced repeatability.
How do impurities or particles affect turbine flow meters?
Turbine flow meters require clean liquids without fibers or solid particles. Particulates may damage the impeller or interfere with rotation, causing signal fluctuation or long-term wear.
Is pulse output suitable for both flow measurement and totalization?
Yes. Pulse output is widely used for instantaneous flow measurement, total flow accumulation, batching control, and system verification, making it highly compatible with PLC, DCS, and industrial automation systems.
