evaporimeter

An engineer checks the evaporimeter in the field.

Definition

1. Noun:
   • A device for measuring evaporation: An "evaporimeter" is an instrument used to quantify the rate or amount of water evaporation from a given surface, typically in meteorology, hydrology, or agriculture. It measures how much liquid water turns into vapor over a specific period.

Usage Examples

• Noun:
  • The meteorologist set up an evaporimeter in the field to monitor daily evaporation rates. (The device was used to measure water loss from the soil.)
  • Farmers rely on an evaporimeter to schedule irrigation, as it shows how much moisture is lost to the air. (The instrument helps determine watering needs.)

Advanced Usage

• "to calibrate an evaporimeter": to adjust or standardize the device to ensure accurate measurements.

  • Before the experiment, the technician calibrated the evaporimeter using distilled water. (The instrument was set to a known standard.)

• "pan evaporimeter": a specific type of evaporimeter that uses a shallow pan of water to measure evaporation.

  • The pan evaporimeter is commonly used in agricultural weather stations. (A water-filled pan is exposed to the atmosphere.)

Variants and Related Words

• Evaporation (n): the process of a liquid turning into vapor.

  • High temperatures increase the rate of evaporation. (The liquid changes to gas more quickly.)

• Evaporate (v): to turn from liquid into vapor.

  • The puddle will evaporate by noon. (The water will disappear into the air.)

• Evaporative (adj): relating to or involving evaporation.

  • Evaporative cooling uses water evaporation to lower air temperature. (The process relies on vaporization.)

Synonyms

• Atmometer: another term for an instrument that measures evaporation (often used interchangeably with evaporimeter).
• Evaporation gauge: a device that records the amount of water lost through evaporation.
