Rain Gauge

Tipping Bucket Rain Gauge – Standard Funnel

RGTB‑6TM is a chrome-plated tipping bucket that collects rain in 0.01″ increments. With each tip, a signal is sent to attached equipment. RGTB‑6 is designed for high accuracy in low- to medium-rate precipitation environments. This tipping bucket rain gauge is best used where precipitation rates are typically below 4 in/hr (100 mm/hr).

PN: RGTB-6.

Description

 

 

The RGTB‑6TM tipping bucket rain gauge with standard funnel provides measurement accuracy in low- and medium-rate precipitation conditions.

RGTB‑6 is made by Hydrological Services, a leading manufacturer of rain gauges offering exceptional value and performance. (This rain gauge was selected after emerging as the leader in Dyacon’s field testing for serviceability, insect protection, construction simplicity, debris screen construction, price, and manufacturing quality.)

RGTB‑6 utilizes a standard funnel catch mechanism that is suitable for low and medium precipitation rates. It employs dual reed switches for switch redundancy and for connecting parallel equipment.

Feature Summary

  • 200 mm orifice
  • Tipping bucket mechanism
  • Integrated leaf filter
  • Machined outlet
  • Easy to service
  • Dual reed switches
  • Varistor protection
  • Encapsulated electronics
  • Discharge collection ports
  • Powder coated aluminum
  • Debris screens

Key Features

Upper Construction

The RGTB‑6TM cast aluminum funnel is mounted to a spun aluminum cylinder. All aluminum is powder coated.

The cylinder is mounted to the base using keyhole slots. The cylinder can be removed without fully removing the screws, minimizing the potential for lost screws while servicing equipment.

Lower Construction

An ABS injection-molded tipping bucket is thick plated with chrome to provide consistent and long-lived performance.

The injection-molded base is made of UV-resistant ABS, which is field proven in desert conditions beyond eight years.

Data Connection

Each bucket tip momentarily closes a reed switch, indicating one incremental step of the gauge resolution.

Dyacon replaces the standard Hydrological Services cable with an outdoor-rated, jacketed cable.

Electronics

The reed switches, varistors, and connector are encapsulated in pliable RTV to prevent cracking from handling and temperature fatigue.

Mounting

RGTB‑6 includes an integrated bubble level. Three-point mounting holes can be mounted to any flat surface.

Accessories

A pole mount, a bird guard, and calibration devices are available.
