The Badger Meter Series 200 flow sensors utilize paddlewheel technology to provide accurate metering on flow velocities from 0.5 to 30 ft/second. Featuring a six bladed impeller design with a proprietary non-magnetic sensing mechanism, Series 200 sensors are available with a number of features which cover applications for a wide range of pipe sizes and pressure/temperature specifications.
Badger Meter Series 200 flow sensors incorporate a number of design elements which improve performance, installation, and maintenance. A forward swept impeller shape provides higher, more consistent torque and is less prone to be fouled by water borne debris. This shape coupled with the absence of magnetic drag provides improved operation and repeatability even at lower flow rates. This is especially true where the impeller is exposed to metallic or rust particles found in steel or iron pipes. The impeller bearing assembly, shaft and o-rings are also replaceable in the field and Series 200 sensors of similar type are interchangeable, so there is no need for recalibration after servicing or replacement.
The Badger Meter Series 200 flow sensors are designed to be used in conjunction with Badger Meter flow monitors or transmitters. An internal preamplifier in the sensor allows the pulse signal to travel up to 2000 feet to the monitor or transmitter without further amplification. The flow monitor also provides the power to operate the sensor.
The Badger Meter Series 200 flow sensors are available in a number of styles.
Model 220 Insertion Sensors
Badger Meter model 220 insertion sensors mount directly to pipes from 3 to 40 inches using a 2 inch NPT pipe saddle or Threadolet for installation. Model 220 sensors can achieve an accuracy of ±1% of full scale on flow velocities of 0.5 to 30 feet/second (±4.0% of reading within calibration range). Brass and stainless steel models are used in most general flow measuring applications in metallic or nonmetallic pipes. The PVC version is designed for service in corrosive liquids.
Model 225 and 226 Hot-Tap Sensors
Badger Meter models 225 and 226 hot-tap sensors are used for flow measuring applications in most metallic or non-metallic pipes where it would be difficult to shut down or drain the line for installation or service. The Model 225 features a gate valve for isolation. The Model 226 uses a ball valve. The sensor mounts in a 2 inch NPT pipe saddle or Threadolet for installation in pipe sizes from 3 to over 40 inches. Model 225 and 226 sensors can achieve an accuracy of ±1% of full scale on flow velocities of 0.5 to 30 feet/second (±4.0% of reading within calibration range). The Badger Meter HTT Hot Tap Tool is required for installation.
Model 228 Tee Sensors
Badger Meter model 228 tee sensors consists of a standard model 220 sensor mounted in a 2 or 2.5 inch tee. Versions of the 228 include a brass/bronze sensors in a bronze tee, a stainless steel sensor in a stainless steel tee, brass/bronze sensors in a cast iron tee, and a stainless steel sensor in a cast iron tee. Model 228 sensors can achieve an accuracy of ±1% of full scale on flow velocities of 0.5 to 30 feet/second (±4.0% of reading within calibration range).
Model 250 Tee Sensors
Badger Meter model 250 tee sensors combine a PPS electronics package inserted in a 1/2, 3/4, 1, 1-1/4, or 1-1/2 inch cast bronze pipe tee with threaded NPT connections. Model 250 sensors can achieve an accuracy of ±1% of full scale on flow velocities of 0.5 to 15 feet/second (±4.0% of reading within calibration range).

Here's how some of our customers used this product.
Heat Exchanger and Boiler Feedwater
The Background: Our customer designs boiler systems for use in large-scale industrial facilities. They seek flow meters to measure the feed water used by their systems.
The Problem: The flow meter needs to installed on 4- or 6-inch pipes and measure the feed water at temperatures of 300°F. Additionally, the customer wants to keep the price below $1500 on each meter.
The Solution: We recommended the Badger 200 Series insertion paddlewheel flow meter which doesn’t use a magnetic sensing mechanism making it ideal for boiler systems and heat exchangers which are often plagued by metallic particles in the feed water. The stainless steel version 220SS is rated up to 300F and costs about $1100. Paired with the Badger 310 pulse-to-analog transmitter, the customer meets their budget and process requirements.
