Can you review what the \"pulse accumulator\" is ? and how can we use it to measure RPM ?

Solution

Pulse Accumulator is a wall mounted, battery-powered electronic recorder of low frequency pulses. It helps users meet their basic data collection needs via a modem and various other forms of wireless technology.

Designed to be either wall or meter mounted, Pulse Accumulator from Mercury Instruments supports most C&I smart metering and AMR analog modem-based applications. Both input channels and stored consumptions can be independently scaled to different units of measure.

Other features include:

Two-channel input: two separate pulse sources can connect to either channel

Call Out or Call In: host or instrument initiated calls

Low power requirements

Shared phone line capability: configurable for line share/line surrender

Audit Trail Capacity: 41 days of hourly/four- user specified log items

Multi-vendor data collection

Wireless communications availability: CDMA, GPRS/GSM, satellite, cellular control channel, radio

Power Control: for battery modem operation

It works as follows:

Two independent pulse sources may be connected to the input channels of the Pulse Accumulator, each having its own 3.5VDC wetting voltage. The two channels act as independent accumulators.

In an operational Pulse Accumulator, pulses received at either input are assigned a fixed amount of volume via their respective Input Pulse Value selections. Additional pulse scaling can be applied using their respective Input Pulse Scaling items (if needed) before the pulses are stored (added) to their respective accumulated totals.

Pulse Accumulator offers maximum value and flexibility in meeting users’ data logging requirements.
