With Rate, Total, Pulse, this ratemeter/totalizer is used for flow rate and total flow measurement from frequency/pulse sensors and batch control with separate batch and rate alarm relays. It has rate accuracy of ±0.1% of reading + 1 LSD.
With Rate, Total, Pulse, this ratemeter/totalizer is used for flow rate and total flow measurement from frequency/pulse sensors and batch control with separate batch and rate alarm relays. It has rate accuracy of ±0.1% of reading + 1 LSD.
The DPF75 is a combination 6-digit totalizer/batch controller and 5-1/2 digit ratemeter with 2 relays. The user can set one relay for batch and the other for rate alarm. The totalizer and ratemeter display in the same engineering units: units per second, minute, or hour.
The DPF75 can accept 2 inputs and separately scale them for "A - B" or "A + B". Either input A rate or net total can be displayed.
