Monitor the load on your pumps with the Digital Load Monitor.
A cost-effective solution, the power monitor is an intelligent control unit that protects your pumps against dry running, end-of-curve operation, and operating against a closed valve and ensures that your pump and motors are always running at their optimal levels. The Digital Load Monitor provides you with a real power measurement for 3-phase AC motors and displays the motor power consumption as a percentage of a selected power range.
Featuring:
The alarm functions activate a single alarm relay which may be used to control the motor being monitored; i.e. to trip a shut-down in the event of either a high or low power alarm.
We are often asked for our recommendation as to the best way to protect pumps against adverse operating conditions: Our recommendation has always been ‘true power’ monitoring (kW). As pump flows change due to demand, tank levels, blocked filters, dry running, etc, then the pump power requirements rise or fall accordingly. True power monitoring allows us to set upper and lower trip points to ensure that the pumps never run dry or operate at a bad operational point thus avoiding poor operating points. Being a power monitor, it is also an instant reaction to a variation in duty and can be set to operate before adverse conditions physically occur. You will be amazed at how successful these units really are.
The digital load monitor is the fastest and most accurate system to protect your pump from the following:
This device measures the true power consumption of 3-phase AC motors and displays consumption as a percentage of a selected power range. The display shows power in units of %kW which represent the percentage of the full load power range for the unit.
As operating conditions on a pump curve change due to dry running, blocked discharge line, closed valves, empty supply tanks, etc, the power monitor automatically trips the motor before mechanical damage and failure to the pump occurs. This is proven technology that eliminates pump failure.
Control functions comprise two independent and programmable trip functions:
The alarm functions activate a single alarm relay which may be used to control the motor being monitored; i.e. to trip a shut-down in the event of either a high or low power alarm.
The Digital Load Monitor is a power monitor that can be configured to monitor any size motor either with the internal current transformer for applications up to 8A or with an external CT for applications above 8A.The power monitor provides consistent sensitivity across the complete motor load range making it ideal for low trip applications where amp meters are ineffective. In addition, the measurement principle allows it to be used on non-sine shaped loads such as Variable Frequency Drives.
