Universal booster amplifier for a coriolis flowmeter |
摘要 |
A universal booster amplifier for a Coriolis flowmeter. The booster amplifier receives drive signals from a flowmeter electronics and extends conditioned drive signals to a driver for flow tubes of flowmeter sensor. The booster amplifier includes phase shift circuitry to provide improved drive signals for flowmeters having curved and straight flow tube geometries. The booster amplifier includes offline switching power circuitry which operates on a plurality of standard AC voltages. The booster amplifier combines environmentally innocuous housing and barrier circuitry to meet numerous regulatory agency safety standards for operating environments including explosive environments and increase the ease of installation and service of the booster amplifier.
