Low Flow Magnetic Flow Meter

Description

The PE102 magnetic flow meter is designed for low-flow chemical injection or difficult-to-meter applications with pulsating metering pumps in 3/4” to 1/4” pipe/tube. The housing is made of sturdy splashproof  HDPE plastic.

With no moving parts, the PE102 can handle fluids containing particulate matter without clogging or jamming, keeping maintenance at a minimum. With no metallic parts (100% PVDF body and PVDF carbon fiber-filled electrodes), the meter is corrosion-resistant and compatible with a wide range of chemicals. Accuracy is maintained with conductive fluids (>20 micro siemens) of varying viscosities and densities.

Accuracy is maintained with conductive fluids (>20 microSiemens) of varying viscosities and densities.

The PE meter is compact enough to fit most pump/injection systems. With zero straight pipe required after an elbow, it can be easily mounted in tight spaces. The mounting bracket adds stability. The PE meter has an optoisolated current sinking pulse output that can be connected to the Seametrics FT430/440 rate/total display or FT520
batch processor, as well as an optoisolated 4-20 mA current loop for powering analog devices. Outputs and power are provided through a 20 foot (6 meter) cable with 8-pin female circular connector.

Features

•  No moving parts
• Requires no straight pipe
• Pulse and/or 4-20 mA output
• Chemical and corrosion-resistant
• Insensitive to fluid density and fluid viscosity changes

Applications

• Chemical injection
• Corrosive materials
• Low flow applications
• Pulsating flows (e.g., metering pump)

OPERATION

The meter will output one pulse when powered up. The newly-installed meter takes from a few seconds to a minute for the signal to stabilize at startup, especially if it has been dry. In normal operation, keep the meter filled with fluid and powered on to prevent this delay. When the meter is mounted properly, an empty pipe detection feature will normally detect absence of liquid in the pipe and register zero flow.

The 4-20 mA signal outputs 4 mA at zero flow and 20 mA at 20 gallons/minute flow or 3 gallons per minute,
depending on model.

\The pulse signal is a 50% duty cycle pulse set at:

• Standard
  • PE202-075: 500 pulses/liter (1892 pulses/gallon)
  • PE202-038: 1,000 pulses/liter (3785 pulses/gallon)
• High Res Option
  • PE202-075: 2641.7 pulses/liter (10000 pulses/gallon)
  • PE202-038: 4989 pulses/liter (18925 pulses/gallon)
