Devices for Irrigation

Irrigation has its own special requirements to the devices used. When no AC or DC power is avalable the devices have to work on a battery but still have a high protection against temperature, moisture, rain and many others.

When power is available it may be advantageous for the device if it uses 25 VAC instead of DC power, which simplifies the wiring and reduces the cost of the installation.

As a standard the flow meters used for irrigation produce very low frequency pulses, sometimes down to one pulse every a few minutes. A typical flow computer will not be able to display a stable flow rate and control its outputs accordingly. Most flow computers will not be able even to show any flow rate and the outputs will not work at all, or will work with huge interruptions and irregularity.

Alarms to shut down the master valve and prevent from flooding and excessive use of water are highly desirable.

Accurate and reliable measurement and control of pumps to add fertilizer, biocides or others to the water for irrigation can reduce the cost dramatically.


Micro Power Flow Computer totalizer NFC101

NFC101 works on a single AA size battery and has an universal input that can accept almost any pulse flow meter with pulses down to one pulse every 5 minutes. It also has a programmable digital output for alarm or pulse and an isolated 4-20 mA output for flow rate.

NFC101E has one inch wider enclosure.

NFCP101 is the panel mount version.

NFC107 works on a single AA size battery, accepts reed switches and dry contacts and has no outputs. It is the lowest cost flow computer / totalizer of this series.

NFC107E has one inch wider enclosure

NFCP107 is the panel mount version.

NFC110 accepts optocouplers, reed switches and others with pulses down to one pulse every 5 minutes. It also has an isolated programmable digital output for alarm or pulse and an isolated 4-20 mA output for flow rate.

NFC110E has one inch wider enclosure

NFCP110 is the panel mount version

NFC110-AC, NFC110E-AC and NFCP110-AC work with 25 VAC or DC power.

High accuracy GMAG100 totalizing magmeter with MODBUS RTU

GMAG100 is a 6.6 GPM max magmeter for water and mild chemicals. With its high accuracy and large turn down it is the ideal flow meter to measure water, fertilizer, biocide, mild chemicals and other liquids. It can accuratelly measure highly pulsating flow which allows to be used with metering and other pumps that produce interrupted and/or fast changing flow. Using its built-in MODBUS RTU communication port it can be programmed at any time to work as a batch controller, flow switch or a flow alarm. GMAG100 also stores the total, which can be read and reset through the MODBUS port.
