Abstract: A pressure transmitter (50) has a pressure sensor (24) coupled to an isolator diaphragm (18L/18H) by a fill fluid (22H/22L) such as oil. Means (52L/54H, 56) are provided for measuring the position of the isolator diaphragm (18L/18H) and comparing the measured position with an expected position to give an indication of fill fluid (22H/22L) leakage.

The fill fluid loss arrangement can be incorporated into a two-wire transmitter, which transmitter can be made to send a warning signal to a control unit when fill fluid loss is detected.

Abstract: A calibrating system calibrates an analog-to-digital converter which has an integrator (20) and first and second reference current sources (IL, IS). A quantity of charge is accumulated in the integrator (20). The quantity of charge is removed from the integrator (20) by applying the first and second reference currents (IL, IS) to the integrator (20) for first and second time periods until the accumulated charge reaches a threshold level. The quantity of charge is reaccumulated in the integrator (20) and again removed by applying the first and second reference currents (IL, IS) for third and fourth time periods wherein the first and second time periods are different from the third and fourth time periods. The relative magnitude of the first and second reference currents (IL, IS) is determined based on the first, second, third and fourth time periods.

Abstract: A vortex flow transmitter (10) has a filtering circuit (20) receiving a noise contaminated input signal representative of the flow and which has a fundamental frequency varying responsively to flow. The filter (20) filters the input signal using one of a family of HP filter characteristics. Each member of the family of HP filters has varying corner frequencies, each filter having a unique switchup and a unique switchdown value assigned to it. Adaptive response means (40) select a current HP filter for use in the filter means. The adaptive means use one selection method when the flow is increasing and another selection method when the flow decreases. Output means (52) convert the signal from the filter means into a transmitter output, typically a 4-20 mA current or a frequency output representative of the flow.
