Rain gauge data logger for long-term rainfall trend recording

HD2013-DB

Rain gauge data logger for long-term rainfall trend recording, storing up to 32,255 tipping bucket pulses with 0.050 to 1.599 mm/sample resolution, IP67 protection and isolated RS232C output.

Introduction

Rainfall monitoring gets complicated when you need long recording autonomy and quick checks on site. HD2013-DB is purpose-built to capture and store rainfall trends from tipping-bucket rain gauges, combining large memory with battery-powered operation for long deployments with minimal user intervention.
 
The backlit display shows rainfall quantities in real time across multiple time windows, including the last hour and the last 4, 24, 48, 72 and 96 hours, plus the rainfall total since the last counter reset. Two reed relays replace push-buttons, keeping the housing waterproof and allowing operation via a supplied magnet tool even in wet conditions.
 
For integration and analysis, the logger connects to a PC through an isolated RS232C serial port (115200 baud) on an 8-pole M12 connector, using the HD32MTLogger software for configuration, real-time monitoring, download and processing. The device accepts both normally open (NO) and normally closed (NC) rain gauge contacts without needing contact-type setup, and the front LED changes color with contact switching to help verify correct tipping bucket return.

Long autonomy
Up to about 5 years typical use with the supplied 3.6 V lithium battery.
Clear trend view
Display shows rain in the last 1, 4, 24, 48, 72 and 96 hours plus total since reset.
Waterproof control
Reed relays operated by magnet avoid external push-buttons for IP67 protection.
Simple rain gauge hookup
Works with NO or NC tipping bucket contacts without contact-type configuration.

Features

Rain gauge event logging

 Counts and stores tipping bucket emptying events and converts them to rainfall using the configured resolution.

Configurable resolution

Resolution can be set from 0.050 to 1.599 mm/sample using the HD32MTLogger software.

Memory management

Stores up to 32,255 samples with cyclic memory management, overwriting the oldest samples when full.

PC connection

Isolated RS232C serial port at 115200 baud via 8-pole M12 connector supports download and configuration.

Status indication

LED blinks red when the rain gauge contact is open and green when closed, supporting quick installation checks.
 

Installation options

IP67 housing can be wall mounted or fixed to the rain gauge support using the HD2003.77/40 clamping for Ø 40 mm supports.
