What's the difference between voltmeter and volumeter?
Voltmeter
Definition:
(n.) An instrument for measuring in volts the differences of potential between different points of an electrical circuit.
Example Sentences:

(8) The design and implementation of high performance differential voltmeters for semi-parallel data acquisition are described.
(9) The circuit can drive a standard pen recorder and digital voltmeter, resulting in rapid and accurate measurements.

(11) A specific implementation of the voltmeters, with separate DC supplies and independent signal references, is described.
(12) The electric potential difference was registered by three independent methods: by transmembrane electrophoresis of penetrating anions PCB-, by direct measurement with using voltmeter in system "proteoliposome--planar membrane" and electrochromic absorption band shifts of bacteriochlorophyll.
(13) Valves connected to the cylinders are sequentially activated by a motor driven shaft provided with cams, which also activates a microswitch connected to a digital voltmeter.
(14) Because this voltmeter is battery powered and is, therefore, completely isolated from all electrical equipment in the operating theatre, it can be used to monitor the presence, or absence, of microfibrillation in the human heart.
(15) To this end, penetrating anion probe and direct voltmeter measurement of electric potential across phospholipid membrane were used.
(16) Light-dependent electric responses of the proteoliposomes were detected using (a) phenyldicarbaundecarborane anion (PCB-) probe and (b) direct measurement by a voltmeter in the proteoliposome-planar phospholipid membrane system.

Volumeter
Definition:
(n.) An instrument for measuring the volumes of gases or liquids by introducing them into a vessel of known capacity.
Example Sentences:
