Siemens Water Ultrasonic Flow Meter

Product Details

Product Description: The wall-mount Ultrasonic Flowmeter is designed to be installed in a fixed location for long-term flow measurement. The FlowSon IT meter is based on transit-time flow measurement principle. It measures the flow rate of liquid in a closed pipe by using a pair of clamp-on or wetted ultrasonic transducers. In general, the liquid should be full in the pipe, and should contain no or small number of particles or air bubbles. Examples of applicable liquids are: water (hot water, chilled water, city water, sea water, etc.); sewage; oil (crude oil, lubricating oil, diesel oil, fuel oil, etc.); chemicals (alcohol, acids, etc.); waste water; beverage, liquid food, solvents and other liquids.The state-of-the-art technologies such as advanced signal processing, low-voltage transmitting, small signal receiving, self-adaptation, the latest electronics, etc., are aimed to achieve high accuracy and reliable performance. Besides, the product provides versatile output interfaces, both analogue and digital, which can be easily used by a host computer or a flow controller.Flow Measurement Principle: The FlowSon IT ultrasonic flow meter is designed to measure the velocity of liquid within a closed conduit. It uses the well-known transit-time measurement principle, plus our proprietary signal processing and ultrasonic transcribing technologies.As shown in Figure 1, the utilizes a pair of ultrasonic transducers which are mounted on the pipe upstream and downstream respectively. Each transducer functions as both ultrasonic transmitter and receiver. The main unit operates by alternately transmitting and receiving a coded burst of sound energy between the two transducers. The transit-times in the upstream direction as well as in the downstream direction are measured. The difference of the two transit times is directly and exactly related to the velocity of the liquid in the pipe."M" is the number of times the sound traverses the flow D is the pipe diameter"Tup£ is the time for the beam travelling from upstream the transducer to the downstream transducer"Tdown" is the time for the beam travelling from the downstream transducer to the upstream transducer"ΔT" = Tup – TdownThe FlowSon CT flow meter can be applied to a wide range of pipe flow measurements. Applicable liquids include pure liquids as well as liquid with small quantity of tiny particles. Examples are: • Water (hot water, chilled water, city water, sea water, waste water, etc.); • Sewage with small particle content; • Oil (crude oil, lubricating oil, diesel oil, fuel oil, etc.); • Chemicals (alcohol, acids, etc.); • Plant effluent; • Beverage, liquid food; • Ultra-pure liquids; • Solvents and other liquid The FlowSon CT flow meter can be applied to a wide range of pipe flow measurements.
