Flash flooding a problem?
Install an early warning system so you can prevent damage!

Rain GaugeThe recent spate of storms and flash floods across eastern Australia has highlighted just how vulnerable we are to these increasingly common weather events. Many businesses have lost thousands of dollars worth of stock and equipment, not to mention the loss of business income and damage to premises.

Have you thought what would happen if a large storm causes flash flooding at your business premises at 3am when you are sound asleep at home? You wouldn't even know about it, and nobody would be on site to take protective measures. The damage bill could be huge.

Esis Heavy Rainfall Warning System

The Esis Heavy Rainfall Warning System provides 24 hour monitoring of rainfall levels at your premises. This system is constantly measuring the rainfall level in mm, and it will trigger an alarm if there is more than a preset amount of rainfall in a given period of time. Alarms are sent to you immediately via SMS or telephone, to alert you when there is a high rainfall event occurring.

The rain alarm can be adjusted to trigger on a certain amount of rainfall in a given period, for example 60mm of rain falling within 2 hours. You can then have it configured to send SMS messages to multiple mobile phone numbers, or if configured with a landline dialer, it can dial up to 16 phone numbers in sequence, playing back a pre-recorded message to each person until someone acknowledges the alert.

The system also includes a surge protection unit and a battery backup power supply, so even if the storm results in a power failure, it will still be able send out the warning messages. A key lock prevents unauthorised changes to the settings.

The Esis Heavy Rainfall Warning System includes the following:

RS2 Rainfall Sentry Pump Controller

The RS2 Rainfall Sentry Pump Controller monitors the rainfall and operates an alarm relay when a programmable amount of rain falls within a programmable period of time. The relay is released after a second programmable period of time has elapsed. This second period of time may be extended, if desired, by further rainfall. The operator may also program the amount of this additional rain, and the extended time period. A SPDT 1 Amp  relay provides voltage free contacts to operate external equipment. An external heavy duty relay or contactor is required to control a pump motor.

Wind Alarm Station

The µSMART Wind Alarm monitors the wind speed and optionally, the wind direction and provides
visible and audible alarms when the readings are out of the user set limits.
The alarm settings include…
• The wind speed threshold and whether the alarm should sound above or below this value.
• The centre direction of the alarm arc.
• The total alarm arc width.
• The time period for which the wind conditions must persist before the alarm is triggered.
• The time period for which the wind conditions must desist before the alarm resets.

This uses the WA1  Alarm Control Unit with LCD display described above, and also requires wind sensors.
Please contact Esis with your requirements.

A Wind Characteristics Station is also available which provides real time information on wind speed, wind gusts, wind run and  wind direction with sine & cosine for sigma theta calc (std dev).

WA1  Alarm Control Unit with LCD display

WA1 Alarm Control UnitWA1  Alarm Control Unit with LCD display (backlit) and push button menu system.
Connect any two sensors, such as wind speed and wind direction - useful on building sites, or temperature & humidity.
If over/under (or both) the preset points it gives either
     an audible alarm
(beep-beep-beep)  or  bright Xenon lampflashes (factory setting, specify when ordering).
     There is an additional cost if both audible AND visible alarms are required.
Can set time delay before alarm proceeds.
The two channel LCD readout shows an asterisk next to the channel in an alarm condition.
Mount where personnel can see it.    Includes mains adaptor. 9-28VDC.  
Optionally, can use solar panel and internal battery.

Environmental Sensors

Monitor Sensors' µSmart environmental sensors have alarm outputs.

They are designed with reliability, robustness, low power requirements and accuracy with added sophistication as follows.

They can be used with a weather station or separately. Each µSmart sensor incorporates a microprocessor providing linearised and standardised outputs, 16 bit resolution (1 part in 65,000) and output signals: analog, ASCII data output/input via serial interface, pulse, control & alarm outputs.
