Ultrasonic flow meter for DN 20 for stable and low-maintenance measurement of liquid flows in pipelines JUMO flowTRANS US W01 Ultrasonic Flow Meter DN 20 (3/4") In pipelines with medium nominal diameters, this flow meter enables reliable measurement of liquid flows under changing operating conditions. The ultrasonic technology operates without contact and delivers stable measurement values without being influenced by parameters such as pressure, temperature, or conductivity. The volumetric flow rate is determined by evaluating signal transit times measured along and against the direction of flow. The difference between these transit times is used to calculate the flow velocity and convert it into a flow value. This makes the system suitable for both steady and dynamic flow conditions. By eliminating mechanical components, the measuring point remains wear-free and requires minimal maintenance. For optimal results, the medium should have a homogeneous composition with only minimal gas or solid content. Advantages Reliable measurement under changing flow conditions Independent of conductivity and other media properties Suitable for continuous monitoring in piping systems Low maintenance requirements during operation Technical Data Measuring principle: Ultrasonic transit-time difference method Nominal diameter: DN 20 (3/4") Measurement setup: Ultrasonic sensors with external evaluation unit Measured variable: Volumetric flow rate Installation condition: Homogeneous liquids with low gas and solid content Typical Applications Water distribution and supply systems Technical systems in industrial environments Process pipelines with varying flow rates Building services and utility installations Frequently Asked Questions Does the device work even with low flow rates? Yes, it detects even very low flow rates and provides stable readings. How long does it take to install it in an existing system? Usually just a few minutes — no lengthy preparations are required. Does the device affect the flow? No, the ultrasonic measurement takes place without any obstruction in the pipe. Do I need to adjust anything afterwards? In many cases, no readjustment is necessary — it works straight away. Does it also work with water of different hardness levels? Yes, whether hard or soft water — the measurement remains stable. Do I need a special mounting kit for installation? Yes, JUMO offers suitable mounting kits separately to make installation even easier and safer.

Ultrasonic flow meter from JUMO for low-maintenance and precise measurement of liquids in piping systems JUMO flowTRANS US W01 Ultrasonic Flow Meter DN 32 (1 1/4") This ultrasonic flow meter enables precise and continuous measurement of liquid flows in pipelines without being affected by typical influencing factors such as pressure, temperature, or conductivity. This makes the system particularly suitable for applications where stable measurement values are required even under changing operating conditions. The measurement is based on the proven transit-time difference principle. Ultrasonic pulses are transmitted through the medium between two sensors. The flow velocity is calculated from the difference in signal transit times in the direction of flow and against the direction of flow, and the flow rate is then determined from this value. This method allows reliable measurement under both constant and varying flow conditions. As the flow meter operates without moving parts, there is no mechanical wear. This significantly reduces maintenance requirements and the risk of failure compared to conventional flow meters. Accurate measurement requires a largely homogeneous medium with only low levels of solids or gas content. Advantages of the JUMO flowTRANS Ultrasonic Flow Meter Measurement independent of pressure, temperature, viscosity, and conductivity No moving parts, resulting in low maintenance requirements Proven transit-time difference method for stable measurement results Suitable for long-term and continuous monitoring Technical Data Measuring principle: ultrasonic transit-time difference method Nominal size: DN 32 (1 1/4") Measurement setup: 2 ultrasonic sensors + transmitter Measured variable: volumetric flow rate (based on flow velocity) Signal processing: transit-time measurement in and against the flow direction Typical Applications Flow measurement in water supply and utility systems Industrial process monitoring of liquids Building services and technical installations Consumption and quantity measurement in pipelines Frequently Asked Questions What do I need this ultrasonic flow meter for?

How accurate are the readings? The measurement accuracy is approximately ±2% of the measured value.

Ultrasonic flow meters Ultrasonic flow meters work largely independently of the specific properties of the product to be measured, such as pressure, temperature, viscosity or conductivity. Due to these advantages, they can be used in a wide range of applications. A further advantage of these systems is that they have no mechanical parts and are therefore less susceptible to maintenance than other flow meters. Principle of ultrasonic measurement: The basis of ultrasonic-based flow measurement is a system consisting of two sensors that communicate directly with each other. In accordance with DIN standard 1319, the flow measuring device consists of two parts: the actual measuring sensor in the form of the ultrasonic sensor and the measuring transducer or transmitter as the evaluation unit. For the measurement, an ultrasonic pulse (sound waves) is sent between the two sensors through the medium to be measured in a pipe. The transit times in the direction of flow and against the direction of flow are measured continuously. It measures the difference in the transit time of these pulses in the direction of flow and against the direction of flow. Without water flow, the signal propagation times in the flow direction and vice versa are identical. If water flows through the measuring section, the propagation speed of the sound waves is accelerated in the direction of flow and delayed in the opposite direction. The transit time difference between the two ultrasonic waves of a data pair is directly proportional to the average flow velocity. To determine the flow volume in relation to a defined period of time (second, minute, hour), the average flow velocity is multiplied by the respective pipe cross-section of the sensor used. The so-called transit time difference method is a proven and widely used measurement method in industrial environments for recording flow volumes. As a result, the meter displays the exact water consumption, regardless of whether the flow rate is high, low, constant or variable. When using ultrasonic flow meters, which work on the basis of the transit time difference method, it is important to ensure that the medium to be measured is as homogeneous as possible and only contains a very small amount of solids or gas. Special feature JUMO flowTRANS US W02 ultrasonic flowmeter The flowmeters utilise wear-free and maintenance-free ultrasonic technology, which enables high-precision measurements regardless of conductivity. Thanks to the metal-free housing and plastic pipes with different nominal diameters, they can be used flexibly, even in corrosive media. Temperature and pressure sensors can also be integrated.
