Electromagnetic water meter for district metering of potable water and custody transfer (CT) measurement
Restricted use in gas and steam applications: As electromagnetic flow meters are made for measuring liquid flow, they're not suitable for gas or steam programs. The shortage of electrical conductivity in these media stops the generation of the measurable induced voltage.
Flow tube disorders: The insulating liner of the flow tube have to be intact and free from damage or build-up. Any compromise while in the liner integrity, for instance scaling, pitting, or fouling, can negatively effects efficiency and will produce inaccurate flow readings.
Orifice flow meters are the preferred liquid flow meters in use nowadays. An orifice is just a flat bit of steel with a particular-sized hole bored in it. Most orifices in use are on the concentric kind, but eccentric, conical (quadrant), and segmental models may also be readily available.
Making certain that water fills the pipe and installing the sensor at the right angles as per set up guides helps stop air bubbles, which could impression the precision of the readings.

Mining and mineral processing Slurry flow measurement to improve the extraction and processing of minerals
In conclusion, magnetic flow meters, with their capability to correctly evaluate flow prices in different problems, give immense Added benefits in a range of industrial programs.
Seamlessly connecting with monitoring devices, the W-Sensor is able to transferring the captured analog meter values to empower successful approach Manage and checking.
And, the measurement precision of the aspect has to be superior in excess of an inexpensive range. The secondary factor steps the differential stress and delivers the signal or go through-out that may be transformed to the particular flow value. Orifice Flow Meters
Furthermore, it eradicates the necessity to compensate for modifying temperature and force conditions. The meter is especially valuable for measuring liquids whose viscosity differs with velocity at specified temperatures and pressures. Coriolis meters are also obtainable in a variety of models. A favorite device is made of a U-shaped flow tube enclosed inside a sensor housing connected to an electronics unit. The sensing unit could be set up immediately into any approach. The electronics unit might be Positioned as many as five hundred toes with the sensor. Within the sensor housing, the U-formed flow tube is vibrated at its all-natural frequency by a magnetic unit Situated on the bend from the tube. The vibration is similar to that of a tuning fork, masking a lot less than 0.1 in. and completing an entire cycle about eighty periods/sec. Since the liquid flows in the tube, it is actually pressured to take on the vertical movement of your tube, Fig. seven. Once the tube is shifting upward in the course of half of its cycle, the liquid flowing more info into your meter resists being pressured up by pushing down within the tube. Figure seven
