A differential transformer recording system, measuring changes in the level of the zinc chloride solution used to float sensitive lysimeters measuring evapotranspiration and dew, recorded errors arising from temperature changes in the solution. Since zinc chloride has certain advantages for use in floating the lysimeters, various methods were devised for compensating for these errors. Although complete correction was not obtained, the temperature errors were reduced to insignificant values with the use of a double float in a stilling well radially divided.
