Rain Gauge Recording Type- Engineering Lab Training Systems.
This natural syphon type recording rain gauge is designed to give
continuous record of rain fall. It is generally used in conjunction with
an ordinary rain gauge (non recording type) exposed close by Rain water
enters the gauge at the top of the cover and is carried through the
funnel to float chamber provided with a float. The recording pen is
mounted on the stem of the float. As the water level rises in the
receiver, the float rises and the pen records rain on a chart placed on a
clock drum which revolves once in 24 hours. The recording mechanism is
mounted on the base and the base cover is provided with a gunmetal rim
of about 203 mm. dia. The funnel lifts of the base and carries hasp
which is engaged with a staple on the base and pad locked. an angle iron
piece with foundation bolt is provided for anchoring the rain gauge
base to the ground. The dimensions of the base, collector, funnel, float
chamber, float etc. are as per ISI specialization No. 5235, 1969 and
also as per IMD specification No. 60A. The unit is supplied with
100 graph paper sheet, a phial of special recording ink, recording pen,
filter, clock movement with drum and key, float chamber with float,
foundation angle iron and literature booklet.
(b) Spare Rain Gauge Charts Per packet of 100 chart sheets.
(c) Spare Recording Ink Phial containing about 20m!. of the Special type of ink.
