Abstract

Water is the life blood of many areas such as the South West part of the United States. Historically, considerable legislation has been passed to make water usage equitable. Recently there has been enacted or proposed legislation that will require closer monitoring of water use. This includes the amount of water being pumped by wells. Many of these wells are in remote locations where utilities are not available. Diesel powered pumps are used for the well so power lines are not needed. Devices for monitoring the flow have been developed and are on the market. Obtaining data from these devices at the wells is often not readily possible.

  IRIDIUM REMOTE MONITORING SYSTEM

by Robert H (Bud) Johnson

  Water is the life blood of many areas such as the South West part of the United States. Historically, considerable legislation has been passed to make water usage equitable. Recently there has been enacted or proposed legislation that will require closer monitoring of water use. This includes the amount of water being pumped by wells. Many of these wells are in remote locations where utilities are not available. Diesel powered pumps are used for the well so power lines are not needed. Devices for monitoring the flow have been developed and are on the market. Obtaining data from these devices at the wells is often not readily possible.

  The Iridiumm satellite system could be used to obtain data from the remote wells and forward to a central location to meet water use requirements. The ground unit would be a modified IridiumTM unit set up for receiving the water flow information. Some means of remote power would be provided such as a solar panel, adding a generator function to the diesel pump, or developing a means to power off the water monitoring equipment. The concept is illustrated in Figure 1. It could also be used on other satellite systems as well & Iridiumm.

  The recent water agreements and water rights legislation requires continuous monitoring of not only remote irrigation pumps but also canals, stream flow and dams to determine water levels and usage. These are typically in very remote areas where power and communication capability are not avail- able. Accordingly, it could be very advantageous to have the same fully automated remote meter reading system for the other applications. The equipment could use Iridiumm or other satellite based commu- nication systems or Cellular phones modified to convey the required data. Other applications could be for oil fields, effluent flows or other areas requir- ing monitoring of flows.

  In addition to monitoring the water flow, the Iridiumm system could be used to also receive data

from a central location for control of the pump, maintenance or other functions. A controller pro- vides the interface between the monitoring equip- ment and the IridiumTM transceiver. An appropriate code would be used to identify the site. The trans- ceiver would be queried at the required time to mee...
