Transmitters Series 340N2 Btu Transmitter with Pulse and N2 Communication

Series 340N2
Programmable Btu Transmitter

The Data Industrial^® Series 340N2 Btu transmitter from Badger Meter is an economical, compact device for sub-metering applications using Johnson Controls Metasys^® Network Companion™ and Facilitator™ Supervisory Systems.

The Series 340N2 calculates thermal energy by measuring liquid flow in a closed pipe hydronic system by integrating the flow and temperature inputs. The Series 340N2 can accept  the signal from any Data Industrial raw pulse flow sensor, as well as many other pulse and sine wave devices. Temperature inputs are accepted from standard 10K Ω (Type II) thermistors.

The on-board microcontroller and digital circuitry make precise measurements and produce accurate, drift-free outputs.The Series 340N2 is commissioned using Badger Meter Windows^® based software.Calibration information for the flow sensor, type and pipe size may be pre-selected or entered in the field. When a PC or laptop computer is connected, the same data that is transmitted across the N2 network is shown in real time. This includes flow rate, flow total, energy rate, energy total, supply and return temperatures, and Delta T. 

The Series 340N2 features two LEDs to verify input and output signals.

The pulse output for the Series 340N2 is an isolated solid state switch closure that is user programmed for units of energy or flow. The output pulse width is adjustable from 50 ms to 5 sec.

The N2 output is an RS-485 complian signal.

The Series 340N2 operates on AC or DC power supplies ranging from 12 to 24 volts.

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