Removable Horizontal Dry Type Woltman Water Meters

Removable Horizontal Dry Type Woltman Water Meters

 An irrigation water meter is a type of water meter designed to measure the amount of water used for irrigation purposes. It is a flow meter that measures the volume of water flowing through an irrigation system.

 The meter can be installed in various places within the irrigation system, such as at the main water supply line, at the point where the water enters the irrigation system, or at individual irrigation zones. The meter can be used to measure the amount of water used for agricultural purposes, landscaping, and other irrigation applications.

 Irrigation water meters can be either mechanical or digital, and they can be equipped with various features such as remote monitoring capabilities, programmable alarms, and data logging functionalities. The data from the meter can be used to calculate water usage, track water consumption, and identify potential leaks or other issues with the irrigation system. This information can help users to manage water usage more efficiently and reduce water waste.

The Operation Description Of The Two Reed Switches System

Please see the diagram of the two reed switches system below, the two reed switches woud be operated “ON” OR”OFF” respectively by the magnet fitted to the pointer or gear during its running on the register, but never “ON” at the same time ,unless the out- magnet attackes.

The two reed switches operate two “ON” and two “OFF” in one round of the pointer or the gear means one signal output, this principle prevent the loss or overcounting of the signal output due to the switches joggling or the pipe vibrating, so assures reliability of the signal output.

Warranty

All meters will be guaranteed against defects in workmanship and materials for a period of one (1) year from the date of acceptance. Defective meters or parts discovered within this period shall be replaced without charge upon return to the S.H.Meters.
