MAC Systems offers a range of monitoring and control solutions for electric and diesel pump installations. For diesel sites, there are generally two options. For simple or smaller pumping units, we can provide remote starting and stopping, remote monitoring of run state, alerting on shut down, pressure monitoring, flow meter monitoring or flow switch, diesel level, battery voltage and engine speed. We require details of the pump make and model, how the pump is started; whether key or press button and the other additional monitoring requirement that may or may not require additional sensors or relays.

The other option for diesel pump sites, which often can be easier to install, is to connect to a new or existing diesel engine control panel, with modbus RS485 communication. With this option, the diesel engine control panel will provide local protection to the engine, such as monitoring coolant level, engine temperature, oil pressure, operating hours, engine battery voltage, engine speed and other parameters required, and will shut the engine down if any critical parameters are outside of normal operating ranges. With throttle control option, we can also provide the ability to remotely adjust the engine speed and adjust the operating speed. With the connection of our telemetry units to a suitable diesel engine control panel, users can monitor all the parameters being measured as well as receive alerts should the pump shut down. With some diesel engine control panels, we can also read the fault code to provide details of the fault that stopped the engine.

We can also provide a similar solution for electric pumps with two main options. One being to provide a remote start and stop, monitor run state and alert on shut down as an entry level solution. Alternatively, for electric pumps with a VSD that has a modbus communication connection, we can connect to the VSD, read all the measured parameters, raise alerts on shut down, remotely adjust speed setpoints and diagnose fault codes that may arise.

With any pump control system, we always recommend that there is some form of protection fitted, such as a pressure or flow switches; particularly with pressurised systems.

Our pump control and monitoring solutions can be single standalone units with remote access via 4G or can be part of a larger telemetry/radio network that can be integrated into the irrigation scheduling platform.
