| hydrometeorology | <study> That branch of meteorology which relates to, or treats of, water in the atmosphere, or its phenomena, as rain, clouds, snow, hail, storms, etc. Origin: Hydro-, 1 + meteorology. Source: Websters Dictionary (01 Mar 1998) |
| hydrometer | 1. <physics> An instrument for determining the specific gravities of liquids, and thence the strength spirituous liquors, saline solutions, etc. It is usually made of glass with a graduated stem, and indicates the specific gravity of a liquid by the depth to which it sinks in it, the zero of the scale marking the depth to which it sinks in pure water. Extra weights are sometimes used to adapt the scale to liquids of different densities. 2. An instrument, variously constructed, used for measuring the velocity or discharge of water, as in rivers, from reservoirs, etc, and called by various specific names according to its construction or use, as tachometer, rheometer, hydrometer, pendulum, etc.; a current gauge. Origin: Hydro-, 1: cf. F. Hydrometre. Source: Websters Dictionary (01 Mar 1998) |

| hydrometrocolpos | <radiology> Accumulation of secretions in the vagina and uterus, dilatation of the vagina proximal to a congenital obstruction (e.g., imperforate hymen), produces a palpable, fixed midline mass, may cause hydronephrosis, AXR: abdominal mass extending from pelvis, ultrasound: cystic mass posterior to bladder with scattered echoes due to cellular material and blood Cf: hydrometros = uterine dilatation only (obstruction at cervix) (12 Dec 1998) |
| hydrometrograph | An instrument for determining and recording the quantity of water discharged from a pipe, orifice, etc, in a given time. Origin: Hydro-, 1 + Gr. Measure + -graph. Source: Websters Dictionary (01 Mar 1998) |
