Seametrics WTP Series Instruction Manual .PDF
PVC-body turbine flow meter
» In-line, individually-calibrated turbine meter maximizes accuracy
» Turbine rotor is the only moving part, optimizing low-flow performance
» Solid-state pickup
» Electronic register can be meter-mounted or remote
» Available with blind pulse or 4-20 mA output
» Materials are chemical-resistant
» Can be ordered with stub ends (standard) or flanges (optional)
