INTRODUCTION

The Series 380 BTU System from Badger Meter® provides a low cost solution for metering cold or hot systems. The 380DS can accurately measure flow and temperature differential to compute energy. Using BACnet™ or Modbus® RS-485 communications protocols or a scaled pulse output, the BTU System can interface with many existing control systems.

The rugged design incorporates an impeller flow sensor and two temperature probes. One temperature probe is conveniently mounted directly in the flow sensor tee. The second temperature probe is placed on either the supply or the return line depending on installation requirements. These minimal connections help simplify installation and save time.

The main advantage of the Series 380 BTU System is the cost savings over other systems offered on the market today. The integration of flow and temperature sensors, along with metering components provide a single solution for metering. With this system, it will be possible to meter energy where metering had not cost effective.

Ordering System Matrix

Commissioning of this meter can be completed in the field via a computer connection. Setup includes energy measurement units, measurement method, communications protocol, pulse output option, fluid density and specific heat parameters.

Series 380

The 380 combines an electronics package with a PEEK sensor probe inserted in a 3/4", 1", 1-1/4", 1-1/2" and 2" proprietary cast bronze pipe tee with threaded NPT connections.

MECHANICAL INSTALLATION

General

The accuracy of flow measurement for all flow measuring devices is highly dependent on proper location of the sensor in the piping system. Irregular flow velocity profiles caused by valves, fittings, pipe bends, etc. can lead to inaccurate overall flow rate indications, even though local flow velocity measurement may be accurate. A sensor located in the pipe can be affected by air bubbles, floating debris, or sediment may not achieve full accuracy and could be damaged. Badger Meter flow sensors are designed to operate reliably under adverse conditions, but the following recommendations should be followed to ensure maximum system accuracy.

1. Choose a location along the pipe where 10 pipe diameters upstream and 5 pipe diameters downstream of the sensor provide no ow disturbances. Pipe bends, valves, other ttings, pipe enlargements and reductions should not be present in this length of pipe.

2. The recommended location for the sensor around the circumference of a horizontal pipe is on top of the pipe. The sensor should never be located at the bottom of the pipe, as sediment may collect there. Locations away from the top-center on a pipe cause the impeller friction to increase, which may aect performance at low ow rates. Any circumferential location is correct for installation in vertical pipes. Rising ow is preferred to reduce eects of any trapped air.

Installing the Sensor Tee

1. Position the tee for unrestricted pipe ow for at least 10 pipe diameters upstream and 5 pipe diameters downstream of the tee.

2. Apply pipe compound over the rst 3 or 4 threads of the mating pipe.

3. Thread the pipe into the sensor tee until hand tight.

4. Tighten the pipe an additional 1-1/2 turns, using a wrench.

ELECTRICAL INSTALLATION

1. The Series 380 requires an isolated 12…24 V AC/DC power supply. To avoid ground fault conditions, the 380 power should not be shared with other devices. This is especially true when the RS-485 network connections are being utilized, where damage to the product or system could result. The power connections are labeled 1 and 2 and are not polarity sensitive.

2. The RS-485 requires three connections: RS-485+, RS-485and REF. The connections are labeled 1 (+), 2 (-) and 3 (GND). RS485 is a high-speed connection and should be wired to meet TIA-EIA-485-A standards. This is especially true if a long cable run is involved or multiple devices are to be networked.

3. The pulse output is a simple solid state switch. The connections are labeled "PULSE OUTPUT 1" and "PULSE OUTPUT 2". The switch is not polarity sensitive, however, be careful that the maximum voltage and current ratings are not exceeded. See "Specifications" on

page 7 for details.

OTE:N The pulse and RS-485 may be used simultaneously.

COMMISSIONING

All setup and commissioning of the Series 380 is done using a USB to Mini USB cable and the Badger Meter Series 380 commissioning software.

Figure 2 shows the main setup screen. Flow and Energy rates and totals can be selected or a custom unit can be put in with the correct conversion factor.

For the temperature sensors the user can select the units along with the calculation mode, i.e., T1>T2, Absolute, or T1<T2. The Diff Zero parameter is the difference between T1 and T2 that will still read 0 energy rate.

If the Scaled Pulse Output is going to be used, the user can select what the pulse is representing (Energy or Flow), along with Units/Pulse and the pulse width. If the Scaled Pulse Output is not going to be used, this output can be set to OFF.

Figure 3 shows the communication parameters tab. The user can select BACnet or Modbus along with the network address. If using BACnet, the Device Name, Device ID BACnet BitRate and the Max Master number should be entered for the appropriate network for which the 380 is being connected.

RS-485 Network Congurations

The RS-485 Section can be configured in two ways:

• Modbus

• BACnet The following sections explain each in detail.

RS-485 Network Configurations—Modbus

Figure 4: Comm parameters—modbus

Select Modbus, to access the Modbus pull-down menus.

Select the Address, Bit Rate (Baud Rate) and Mode (RTU or ASCII).

The Series 380 uses IEEE 754 Float Data Located in “Read Holding Registers.”

The Series 380 Data Format is “Float 32” where the Data is stored across two “Read Holding Registers”.

In the case of sensor mounted in the 380 body, the upper byte is stored in register 40001 and the lower byte is stored in the register 40002.

For example, a temperature of 53.36° F when converted to IEEE 754 is “425570A4.” In the case of the Series 380, Register # 40001 = 70A4 Hex and Register # 40002 = 4255 Hex. See

Table 1 on page 6 for additional information.
