Statement

At the AWS Pyramid Laboratory Observatory station the DQA035 Lsi-Lastem rain gauge is mounted on a 1,5 m mast.

This model of Rain gauge has a 1.000 cmq collector area.

The measurement device is composed of a collector cone and a double chamber bascule connected to a magnete that operates one (optional two) reed switch, which generates impulses that can be counted by external meters: each impulse is equal to 0.2 mm of rain (optional from 0.1 to 0.5 mm).

The mechanical and electrical specifications are:

- Collector surface area: 1000 cmq

- Collector area diameter: 420 mm

- Measurements range: 180 mm/hr

- Resolution: o,2 mm/imp. (opt. 0,1; 0,3; 0,4; 0,5; mm/imp.)

- Accuracy: 0-1 mm/min: 1%

1-3 mm/min: 2%

3-5 mm/min: 4%

5-10 mm/min: 8%

- Contact: 1 reed (opt. N.2 reed) 0,5 A/24V non inductive

- Pulse duration: 100 msec.± 5

- Collector cone material: Brass

- External housing material: Inox AISI30

- Tipping bucket material: Alluminium

- Cable: 10 m

- Weight: 6,3 kg

- Power supply: /thermocover 100 W, 24 Vca/Va
