Description
The 2537 Paddlewheel Flowmeter Series offer low À ow, low power and high resolution with various output options such as a Volumetric
Pulse, Pulse Divider, Flow Switch, Digital (S
interface.
• The 4 to 20 mA model provides a blind current loop output.
• The Digital (S L) model provides a Digital (S
3
• The Multi model uses a single relay (mechanical or solid state) and has three selectable operating modes:
• Divider Mode scales the paddlewheel frequency down to accommodate low frequency input devices.
• Total Mode outputs one pulse per a set volume of À uid.
• Flow Switch Mode uses a single relay for Hi or Lo alarm operation.
A small LCD enables the 2537 to be programmed without any external equipment. During normal operation the display is not visible.
