The series 340 LW BTU transmitter is an economical, compact device for submetering applications that communicate via a Lonworks® network.
The 340 LW calculates thermal energy using the signal from a flow sensor installed in the systems inlet and outlet points. The flow input may be provided by a sensor and many other pulse or sine wave signal flow sensors. The onboard microcontroller and digital circuitry make precise measurements and produce accurate drift free outputs.
The 340 LW is commissioned using Windows® based software. Calibration information for the flow sensor, type and pipe size may be preselected or entered in the field. While the unit is connected to a PC or laptop computer, realtime flow rate and total, temperatures and energy rate and total are available.
