Series 340
Programmable Btu Transmitter

The Data Industrial Series 340 Btu transmitter is an economical, compact device for sub-metering applications.
The 340 calculates thermal energy by measuring liquid flow in a closed pipe system and measuring temperature at inlet and outlet points. The 340 requires two 10 kW thermistors for temperature input. The flow input may be provided by any Data Industrial sensor and many other pulse or sine wave signal flow sensors.
The onboard micro controller and digital circuitry make precise measurements and produce accurate drift-free outputs. The 340 is programmed using Data Industrial’s Windows^® based software and a Data Industrial A301 programming cable. Calibration information for the flow sensor, units of measurement and output scaling may be downloaded prior to installation or in the field. While the unit is connected to a PC or laptop computer, real-time flow rate, flow total, both temperature readings, energy rate and energy total are available.

The Series 340 transmitter features two LED’s to verify input and output signals.

The standard output for the Series 340 is an isolated solid state switch closure that is user programmed for units of energy. The output pulse width is adjustable from 50 mS to 5 Sec.

The Series 340 energy transmitter operates on AC or DC power supplies ranging from 12 to 24 volts.

The compact cast epoxy body measures 3.65"(93mm) x 2.95"(75mm) and can be easily mounted on panels, DIN rails or enclosures.

Once the values are set, the "send" command loads the transmitter.

All programming can be saved with a file name for later reference.

A full explanation of all settings is available through the software help file.
