Abstract
A differential-pressure measuring instrument includes a pair of diaphragms each subject to a respective fluid pressure. The diaphragms enclose a sealed chamber containing a fill-liquid surrounding a non-magnetic vibratable-wire which is tensioned in accordance with the applied differential pressure. A temperature compensating inductor is connected in parallel with the vibratable-wire to compensate for variationsin the vibrating frequency of the wire due to changes in the viscosity of the fill-liquid with temperature.
