H-type flumes were developed to determine widely fluctuating flow rates, from very low to extremely high volumes. For example it is possible to measure seasonally changing discharges or discharges resulting from heavy rainfall events. Furthermore H-flumes are also deployed to record agricultural and industrial discharge processes. On condition that there is an open flume with free discharge on the outlet, they deliver outstanding accuracy even in the case of contaminated water. An upstream stilling channel ensures even distribution of the flow over the entire measurement range.
The H-flumes are manufactured from strong, stainless V2A steel. The water level is gauged in a contactless procedure using ultrasonic transducers or capacitive sensors installed in a V2A protective housing. In combination with UGT data loggers, the temperature and wind compensation of ultrasonic transducers takes place in the data logger.
|We supply H-flumes in three sizes to facilitate optimal alignment to the prevailing flow rate range:|
|1 Ft-H-Flume||30.5 cm||0.02 ... 55 l/s|
|2 Ft-H-Flume||61 cm||0.04 ... 315 l/s|
|3 Ft-H-Flume||91.5 cm||0.06 ... 870 l/s|
