Description

Model : SWOFFER 2100

A portable, reliable means of measuring open stream velocities in the range of 0.1 to 25 feet per second or 0.03 to 7.5 meters per second ( selectable) . Measurements can be read in feet or meters on your choice of two digital readout indicator models, both with better than 1% accuracy. Each meter includes a meter indicator, shoulder strap and snap ring, and PVC shipping/ storage tube for the sensor. 2100 Series includes a 9V battery, and the 3000 series includes four AA batteries.

The sensor uses a 2″ propeller which rotates a fiber-optic bundle to create a signal from a photodiode to a photosensitive transistor. This signal is transferred via cable to the indicator where velocity is displayed. Resolution of the display is to hundredths. The propeller is swivel mounted for easy storage. A quick-disconnect, waterproof cable connection is located at the indicator. The electronics of the sensors are permanently encapsulated in epoxy resin and housed in chemically inert acetal-resin fittings. All sensor parts are replaceable and are available separately. Sensor wands are aluminum alloy with stainless steel fasteners. Propeller is glass impregnated nylon and all other plastic sensor parts are acetal-resin ( Delrin or Celcon) .

Model 2100 Indicator
Accommodates all types of open stream flows. Three selectable, pre-set display update times allow up to 90 seconds of averaging. In extremely turbulent flows, otherwise unreadable data is electronically averaged and can be used without interpolation. Features a dial style control and self-calibration to check accuracy of instrument while in the field. A compartment in the back of the indicator houses the battery and has space for one spare. Liquid crystal display features one line with 0.7″ H digits.
