1. User Manual for RLT-100 Ultrasonic Flow Meter: [5]
The core content of the user manual for RLT-100 ultrasonic flow meter is as follows:
1. Product Overview RLT-100 ultrasonic flow meter is a flow measurement instrument designed based on the principle of ultrasonic propagation time difference, suitable for non-contact measurement of liquid flow in industrial pipelines. Its core advantages include non-invasive installation: no need to cut off pipelines or shut down, direct installation through external clamp sensors, reducing maintenance costs. High precision measurement: using dual channel ultrasonic signal processing technology, the measurement accuracy can reach ± 1%, and the repeatability is better than ± 0.5%. Wide range ratio: The range ratio can reach 1:200, suitable for low flow velocity (≥ 0.01m/s) to high flow velocity (≤ 15m/s) scenarios. Multi parameter display: Real time display of instantaneous flow rate, cumulative flow rate, flow rate, temperature (temperature sensor optional) and other parameters. Strong anti-interference ability: Built in digital signal filtering algorithm can effectively suppress interference such as pipeline vibration and noise.
2. Installation and Debugging Installation Conditions Pipeline Material: Suitable for uniform material pipelines such as steel, stainless steel, cast iron, PVC, PE, etc., avoiding non-uniform materials such as concrete and fiberglass.
. Pipeline size: nominal diameter DN15-DN6000mm, ensuring smooth inner walls of the pipeline without severe corrosion or scaling. Requirements for straight pipe section: The length of the upstream straight pipe section should be ≥ 10DN, and the length of the downstream straight pipe section should be ≥
III. Operation and Display Main Interface Function Real time display of instantaneous flow rate (unit: excavation m ³/h or L/s), cumulative flow rate (unit: m ³), and flow velocity (unit: m/s). Support multi parameter switching display, and view auxiliary parameters such as temperature and signal strength through button cycling. Parameter settings for pipeline parameters: It is necessary to input parameters such as pipeline material, outer diameter, wall thickness, and lining material (if any). Fluid parameters: Set the physical properties such as fluid type (water, sewage, oil, etc.), density, viscosity, etc. Instrument parameters: Adjust range, small signal cutoff threshold, filtering time constant and other optimization par
