Non-recording gauge
Symon's rain gauge is a non-recording type gauge used to measure rainfall at a specific observation station. It does not provide a continuous temporal distribution of rainfall but rather gives the total amount of precipitation occurred between two successive observations.

d=AVтАЛ тАФ Rainfall depth (d) is the ratio of collected volume (V) to the area of the collector (A).
It consists of a cylindrical vessel with a funnel and a receiving bottle inside. The rain collected by the funnel is stored in the bottle; at fixed time intervals (usually 8:30 AM), the water is measured using a graduated cylinder designed specifically for the gauge's dimensions. Because it is manually read, it cannot record the intensity or variation of rainfall over time.
It is the standard non-recording rain gauge used by the Indian Meteorological Department (IMD).
The diameter of the collector is usually 127 mm.
It provides cumulative rainfall data, not intensity.
Manual intervention is required to read the gauge.
Simple in design and construction.
Low maintenance and cost-effective.
Robust and less prone to mechanical failure.
Cannot record the intensity of rainfall.
Requires manual labor for daily readings.
Time of onset and duration of rainfall cannot be determined.
Basic hydrological surveys.
Agricultural monitoring where only daily totals are needed.
Remote areas with limited technical infrastructure.

The standard observation time in India is 08:30 IST.
Tipping-bucket, weighing type, and float-type gauges are all recording types used to plot mass curves of rainfall.
D is correct тАФ Symon's rain gauge is a non-recording instrument that collects precipitation for manual measurement at specific intervals.
Always remember that 'Non-recording' gauges provide depth, while 'Recording' gauges provide intensity (i=dtdhтАЛ).
