UBITO
Flow Metering There are millions of gas and water meters installed all around the globe. Wiegand technology can help service providers and consumers by making these meters smarter and more efficient. A permanent magnet can be mounted on the meter 's rotating shaft, close to a Wiegand sensor. As the shaft turns, the rotation of the magnetic field triggers a pulse. The strength and duration of each current pulse is independent of how quickly or slowly the shaft rotates. This is one of the major benefits... (read more) -

Flow Meter Protection Flow meters are vital to the integrity and accuracy of fluid processing systems, but they are also vulnerable to one common and costly problem: pulsation. Using a pulsation dampener for flow meter protection can significantly reduce flow variability and extend the life of this critical instrumentation. For industries where precision, reliability, and uptime matter most, integrating dampening technology is more than a best practice. It's a cost-saving necessity.

Gurley Precision Instruments
Pygmy Flow & Current Meters The compact design of pygmy meters - the bucket wheel is just 3/4 inch by 2 inches in diameter - allows measurement of shallower and lower velocity flows. The pygmy meter provides reliable measurements of flows down to 0.05 feet per second at depths as shallow as 3 inches. Except for the absence of a five revolution click, these models operate identically to the larger Price type meters in both headphone and digital models. Pygmy meters are rod suspended only. For over 100 years, Gurley has... (read more)Browse Open Channel Flow Meters Datasheets for Gurley Precision Instruments -
