The Trumeter APM Frequency Meter is a programmable digital frequency meter for effective monitoring, measuring and displaying of AC or DC Frequency.

Frequency Meter


Digital Frequency Meter
The APM Frequency Meter has an input range of 2-400Hz and an impressive accuracy of 0.1%. It is suitable for many applications including: 

– mains applications

– generators and power performance monitoring

– industrial applications

– process monitoring

– aviation industry applications 

Because it is a programmable frequency meter, it also can be configured to accurately measure DC pulses. The LCD display, unique to the APM range, incorporates the instant recognition of traditional analogue panel frequency meters with the precision and accuracy of modern digital panel meters.

This combination provides an immediate visual indication of critical parameters and clear accurate readings. This improves performance monitoring, cost effectiveness and increases safety. 

Programmable Frequency Meter
The panel meter comes with 15 pre-loaded configurations or it can be customised to your requirements via the configuration software.

The 40-segment bar graph can be programmed to the scale you require while the positive and negative and centre zero scales can also be configured. The dynamic backlight can be tailored to alert the user whenever a critical parameter is out of set range and the backlit display can be set to flash and/or change colour (or intensity) between red, green and white.

With its two outputs – one analogue, one digital – the panel meter can interface with other systems, including generators, beacons, sounders, or other indicators, for even clearer notification of frequency.

  • 40 segment bar graph display
  • Scale (offset and gain) and Range (min and max)
