Nutating disc flow meter pdf file

All parts are designed and built of materials to meet your application, providing you with long life and a troublefree, precision flow meter. Oscillating piston flow meter working, advantages and disadvantagesdifferential pressure flow meterapplications of nutating disc flow meter nutating disc meter one of the common flow meter, it is used extensively in residential water services measurement, and also it can be used in many industrial applications. Liquid enters a precisionmachined chamber containing a disc which nutates wobbles. Nutating disc meter displacement meter badger meter. The positive displacement nutating disc flow meter uses a precisely machined chamber. Above figure shows the schematic diagram of nutating disc meter. They operate by having a disc mounted to a central ball.

The meter design is based on internationally proven positive displacement nutating disc isolates a fixed volume of liquid and the motion is. Available in five sizes, 12 through 2 for flows up to 170 gpm, these meters are extremely rugged and reliable. The nutations of the disc are transmitted by a gear train to a totalizer or pulse transmitter. When fluid enters the chamber, it causes the disc to wobble nutate, transferring the displaced volume to the register. Nutating disc flow meters are one of the most common types of positive displacement flow meter. A nutating motion of the disc is generated when flow enters the meter chamber. Use the meter only with the liquid for which it was ordered and within the specified limits of pressure, temperature, and flow rate. Positive displacement nutating disc meter niagara meters. Nutating disc flow meters working principle instrumentationtools.

The measuring chamber contains an exact known quantity of fluid. Smcs almpd microflowmeter is a nutating disk positive displacement meter designed for precise measurement of ultralow flow rates. The simple and reliable operating principle allows water to flow into the chamber, which causes the disc to nutate. Maintenance is seldom required, but if necessary, takes only a few minutes.

Liquid flowing through the meter chamber a causes a disc b to nutate or wobble this motion, in turn, results in the rotation of a spindle c and drive magnet d rotation is transmitted through the wall of the meter to a second magnet e or varied style of sensor pickup c b a e d figure 1. Various materials of construction makes flowmeter compatible. With over years of experience, niagara meters produce high quality and highly robust flow meters based on a number of technologies that are suitable for large variety of. Nutating disc flow meter working principle, applications. A nutating disc meter has a measuring chamber that contains a disc that nutates. Combining the accuracy of positive displacement meters with the reliability and economy of nutating disc technology, the rcdls simple but efficient design is wellsuited for measuring the flow of water and other fluids, hot or cold.

Nutating disc meters are the most common and accurate type of positive displacement meters. Nutating disc flow meter working principle, applications, advantages and disadvantages mecholic. The badger meter rcdl nutating disc flow meter is an accurate, cost effective solution for metering industrial fluids. Flow measurement and control badger meter europa flow. Tight machined tolerances for exact amount of fluid for liquid flow measurement. Set the meter between the coupling nuts or in the flange pipline positioned so that the flow arrow on the meter. A ball bearing centralizes the disc between the two spherical cups. Each disc nutation represents a fixed quantity of water, so the total flow is calculated by the total number of nutations. Check all systems for flow of liquid, including valves ahead of the meter. Nutating disc micro flow pd flowmeter smartmeasurement. Nutating disc meters rcdl distributor of flow meters. A short history of positive displacement flowmeters. Smartpd meter nutating disc positive displacement is getting smarter the smartpd positive displacement meter is a volumetric meter that provides total volume and flow rate measurements by way of an electronic transmitter adding closed loop control to your system.
