CDI5100 Inline Flow Meters

Description

The CDI 5100 extends the capability of the CDI 5000 series to the low flow rates found in many point-of-use applications. It does this by concentrating the flow into a small area that is chosen to optimize the tradeoff between pressure drop and low-flow sensitivity. Used in its intended flow range and at a pressure of 100 psig, the 5100 will create a pressure drop no greater than one psi

Feature

  • Accurate measurement of small point-of-use flows
  • Minimal pressure drop
  • Weather resistant and surge protected
  • Milliamp output
  • Pulse output convertible to threshold output
  • User-configurable scaling, filtering and units of measure
  • Optional wired and wireless outputs for networking

Like the other 5000-series flow meters, the 5100 is a thermal mass design, using one probe to sense the air temperature and maintaining the other ten degrees warmer. By concentrating the flow where it passes the two probes, it is able to measure low air flows without requiring small passages that could clog or create excessive pressure drops.

The meter is furnished with a carefully-reamed six-inch piece of size-specific pipe to be installed where the air enters the meter. With this pipe in place, there is no other requirement for flow conditioning or straight upstream pipe. The meter may be installed between quick disconnect fittings to test air usage by small pieces of equipment.

Product Description

CDI-5100-03S-20

£590.55

CDI 5100 Inline flowmeter for compressed air and Nitrogen with 4 digit LED display. Outputs 4-20mA and pulse. 3/8″ NPT thread with 20scfm range. Accuracy 2% of reading, plus 0.5% of indicated range. Power Supply: 24vDC @ 250mA (unit supplied with UK mains power supply with 1.5m cable). Operating pressure 200 psig Max. A 6″ length of pipe is supplied to ensure proper flow into the meter.

CDI-5100-05S-40

£647.24

CDI 5100 Inline flow meter for compressed air and Nitrogen with 4 digit LED display. Outputs 4-20mA and pulse. 1/2″ NPT thread with 40scfm range. Accuracy 2% of reading, plus 0.5% of indicated range. Power Supply: 24vDC @ 250mA (unit supplied with UK mains power supply with 1.5m cable. Operating pressure 200 psig Max. A 6″ length of pipe is supplied to ensure proper flow into the meter.

CDI-IPO

£33.06

Isolated Pulse Output Module for the CDI flow meters. The pulse output built into CDI flow meters is an open-collector transistor output that functions as a switch to the meter’s ground. It does not provide electrical isolation between the meter and the receiving device. The CDI-IPO provides this isolation.

CDI-SC

£99.23

RS-485 Serial Communications Module for the CDI Flow Meters

CDI-PSO

£174.84

CDI-PSO Pressure Sensing Option for the CDI compressed air flow meters. Range 0-145 PSIg (0-10 BarG). Output 4-20mA. Only available one new meters and not available as a retrofit to existing meters.
