Gas, Water and Heat Flow Meters

As gas/water meters continue to pursue lower power consumption the need for highly efficient power supplies and low leakage parts become paramount. Microchip Technology has developed an analog portfolio to help meter designs achieve the next generation targets by lowering both quiescent and operating currents.

A portfolio of precision op-amps help designs achieves the next level of low-cost precision measurements for mechanical meters, ultrasonic flow measurement, and temperature readings. Ultrasonic flow meter designers can significantly reduce cost with a simple yet precise analog signal conditioning circuit coupled with a Microchip MCU with integrated a charge time measurement unit (CTMU).

Features

• Low quiescent current to maximize battery life
• I²C™ temperature sensors with 0.5 accuracy

• Fewer components with LDOs
• Low-noise op-amps
