Description

The DPF400 Series is a complete line of flowrate indicators offering exceptional performance at an economical price. Individual models are available for flowrate and totalization (with or without square root extraction) batch control.

The DPF400 is front panel programmable to scale any input range to display in desired engineering units. Independent scale factors for rate and total allow rate indication and totalization in different units, such as GPM rate and total barrels. If the optional RS-232 or RS-485 communications are installed, the unit may also be programmed by remote computer.

The DPF400 is available with 4 input types, including TTL/open collector pulse, low level frequency, analog voltage or analog current. The unit can be user-configured for one of three functions:
  1. a ratemeter/totalizer/batcher
  2. a ratemeter/totalizer/batcher with square root extraction (for differential pressure flow measurement)
  3. a batch controller only with multibatch counting, auto/manual batch recycle, and remote or local STOP/CONTINUE control (START control can be obtained with a user supplied switch in series with the control relay)
Options to the DPF400 include analog and BCD outputs, alarm/control outputs, and RS-232 or RS-485 communications.

The RS-232 or RS-485 communications options are bi-directional, allowing the user to configure the DPF400 as well as read current values.

While each DPF400 comes standard with 5 open collector outputs, the optional DP40-R board provides dual 7A mechanical relays which replace two of the open collector alarms, for a total of two 7A relay and three open collector alarms.
