You can configure both preprogrammed and user-defined units of measure . The Series 3050 BTU flow monitor accepts pulse or linear analog input signals . Like all Badger Meter flow monitors, the Series 3050 BTU flow monitor may be field-calibrated . For Badger Meter sensors, K and offset numbers are entered, while other pulse or frequency output sensors may use a K-factor only .
Installation INSTALLATION Mechanical Installation The Series 3050 BTU flow monitor can be either panel-mounted or wall-mounted . Location In any mounting arrangement, the primary concern is easy viewing and convenient operation of the keypad . The unit generates very little heat, so no consideration need be given to cooling or ventilation . However, prolonged direct sunlight can damage the front panel so some level of shading is recommended, especially if installed in a tropical climate .
Installation Wall Mount Installation The Series 3050 BTU flow monitor wall-mount model is designed to mount onto a wall with four bolts or screws . The mounting hole pattern and box dimensions for the Series 3050 BTU flow monitor NEMA4 waII-mount model are shown in Figure 4.33 in.
(ACC/DC-) . If a Badger Meter plugin power supply (Model A-1028) is being used, connect the black-white wire to the terminal marked (ACL/DC+) and the black wire to the terminal marked (ACC/DC-) .
The Series 3050 flow sensor inputs are extremely versatile, designed to accept either two-wire or three-wire pulse inputs (Badger Meter 200 Series, SDI or 4000 Series) or Analog inputs . Although different rear panel terminals are used, all parameters are set with the LCD/keypad interface . There are no internal or external jumpers, switches or potentiometers to move or adjust .
Installation Analog Input As an alternative to the pulse inputs, the Series 3050 BTU flow monitor can accept an Analog input . The input is non-isolated, but can accept 0…1V DC, 0…5V DC, 0…10V DC, 0…20 mA and 4…20 mA with both factory-defined and custom units of measure .
Installation Temperature Input The Series 3050 BTU flow monitor can accept inputs from either a pair of thermistors or RTDs . The inputs are labeled T1 and T2 . Since the T1 sensor is used to convert the volumetric flow (Example: GPM) to the mass flow (Example: Lbs/Hr) used in the BTU calculations, the sensor connected to T1 should be in the same supply or return line as the flow sensor .
Installation Solid-State Switch and Form C Output Wiring The Series 3050 BTU flow monitor has one Normally Open (N .O .) solid-state switch, and one solid-state Form C relay . See the "Specifications" on page 30 for maximum voltage and current ratings for each type output . These outputs are completely independent, electrically isolated, and can be programmed as either Pulse or Setpoint outputs .

When the Series 3050 BTU flow monitor is first powered up, it runs through internal self checks while displaying “Badger Meter DIC Initializing." At the end of this cycle its normal mode display will appear . In the normal mode, if still using the factory defaults, flow rate will be displayed on the top line, and flow total displayed on the bottom .
Programming PROGRAMMING With the normal mode display showing, press Menu to enter the programming mode . In this mode, you use the three arrow keys () on the selection screens to select the option displayed above the key, and on the option list screens to scroll up or down a list of choices, like a pull-down menu .
