Installation & Operation Manual

INTRODUCTION

Used in conjunction with any Badger Meter Impeller flow monitor or endpoint, Badger Meter non-magnetic Impeller flow sensors provide an accurate reading of the rate of liquid flow as well as total accumulated flow. A number of sensor models are offered, which cover applications for a wide range of pipe sizes and pressure/temperature specifications.

The flow sensors generate a frequency which is proportional to flow rate. An internal preamplifier allows the pulse signal to travel up to 2000 feet without further amplification. Power to operate the sensor is provided by the flow monitor. The impeller bearing assembly, shaft and o-rings are replaceable in the field.

Badger Meter Impeller flow sensors feature a closed, six-bladed impeller design, using a proprietary, non-magnetic sensing technology. The forward-swept impeller shape provides higher, more constant torque than four-bladed impeller designs, and is less prone to fouling by water-borne debris. The forward-curved shape, coupled with the absence of magnetic drag, provides improved operation and repeatability, even at lower flow rates. As the liquid flow turns the impeller, a low impedance signal is transmitted with a frequency proportional to the flow rate.

Sensors of similar type are interchangeable, so there is no need for recalibration after servicing or replacement.

ELECTRONIC TYPES

Badger Meter provides several basic sensor configurations using the same impeller element. This allows for a wide range of applications and pipe sizes. Sensors are normally supplied with 20 feet of 2-conductor 20 AWG shielded U.L. type PTLC 105° C cable. Optional sensors designated with the prefix "IR" feature two single conductor 18 AWG solid copper wire leads 48 inches in length with U.L. Style 116666 direct burial insulation. These IR models are used in below grade applications such as irrigation, municipal, and groundwater monitoring. All Badger Meter Series 200 sensor electrical components are self-contained. Pressure/temperature ratings for the various models are contained in "SPECIFICATIONS" on page 10. These models can be further described as follows.

Standard Sensor

Designed for indoor or protected area applications such as HVAC, pump control, and industrial process monitoring where the flow rates are between 0.5…30 feet/second and temperatures are below 221° F. Standard sensors are supplied with 20 feet of 2-conductor 20 AWG shielded U.L. type PTLC 105° C cable.

IR Sensor

Designed for below grade applications such as irrigation, municipal, and groundwater monitoring where the flow rates are between 0.5…30 feet/second and temperatures are below 180° F. IR sensors are supplied with two single-conductor, 18 AWG solid copper wire leads 48 inches in length with U.L. Style 116666 direct burial insulation.

CSA Sensor

Designed for indoor or protected area applications where intrinsic safety is required and the flow rates are between

0.5…30 feet/second and temperatures are below 140° F. CSA sensors are supplied with 20 feet of 2-conductor 20 AWG shielded U.L. type PTLC 105° C cable. These sensors must be used with an approved safety barrier.

Model 228PV (Formerly 220P)

These models feature a modified PVC tee with solvent weld socket end connections, and a removable, PPS or PVDF sensor insert. Sizes of 1-1/2", 2", 3" and 4" are available.

MECHANICAL INSTALLATION

Depressurize and vent the piping system prior to any installation or maintenance of the flow sensor.

General Information

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, or other obstructions can lead to inaccurate overall flow rate indications, even though local flow velocity measurement may be accurate. A sensor located in the pipe where it 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:

• Choose a location along the pipe where 10 pipe diameters upstream and 5 pipe diameters downstream of the sensor provide no flow disturbance. Pipe bends, valves, other fittings, pipe enlargements and reductions should not be present in this length of pipe.

• The preferred location for the sensor around the circumference of a horizontal pipe is at the 12 o'clock position. The sensor should never be located at the bottom of the pipe, as sediment may collect there. Locations off top dead center cause the impeller friction to increase, which may affect performance at low flow rates and increase wear. Any circumferential location is correct for installation in vertical pipes, with rising flow preferred to reduce the effects of any trapped air.

Mechanical Installation Procedure

1. Note the intended direction of ow as indicated by arrows on the tee. There must be free, unrestricted pipe for at least 10 diameters upstream and 5 diameters downstream of the tee.

2. Remove the clevis pin and remove the sensor from the tee.

3. Properly clean the pipe ends and tee sockets.

4. Use solvent cement to attach the pipe to the tee.

5. Reinstall the sensor in the tee as follows:

a. Align the flow arrow on the top of the sensor housing in the direction of flow. b. Carefully press the sensor straight into the tee. c. Install the clevis pin through the tee, the sensor, and the conduit cap, and install the cotter ring.
