What is The Digital Flowmeter?

EXAIR's Digital Flowmeter is the easy way to monitor compressed air consumption and waste! The digital display shows the exact amount of compressed air being used, making it easy to indentify costly leaks or inefficient air products. Many companies install the Digital Flowmeter on each major leg of their air distribution system to constantly monitor and benchmark compressed air usage.

Why The Digital Flowmeter?

The Digital Flowmeter has an LED display that directly indicates the SCFM or m3/hr volume of airflow through that pipe. Model from 1/2" to 4" iron pipe are in stock. Each Digital Flowmeter is calibrated for the pipe size to whic it is mounted.

The Digital Flowmeter is designed for permanent or temporary mounting to the pipe. It requires the user to drill two small holes through the pipe using the included drill bit and locating fixture. The two flow sensing probes of the flowmeter are inserted in these holes. The unit seals to the pipe once clamps are tightened. No cutting, welding, adjustments or calibration are ever required. If the unit needs to be removed, blocking rings are available. NEMA Type 4 (IP66) meters available.

Advantages:

• Easy to install - No Moving Parts
• Summing Remote Display and Data Logger available
• Optional RS-485 output serial communication board available
• Sensitive at low flows
• No calibration or setup required
• Includes all components for installation
• Models from 1/2" to 4" Schedule 40 iron pipe in stock
• Models are available for sizes 1/2" to 6" in iron pipe
• Models are available for sizes 3/4" to 4" in copper pipe

Flowmeter Versions

 

 Standard

The original Digital Flowmeter provides accuracy and an easy to read display of current compressed air consumption, daily consumption or cumulative consumption. Digital Flowmeter with optional Data Logger shown at left.

 Wireless 

Transmit the compressed air data wirelessly over a ZigBee mesh network! A radio module within each meter transmits data to an Ethernet connected gateway. Using the ZigBee mesh network protocol, data can be passed from meter to meter to extend the distance over which the wireless system can operate. Each meter has a range of 100' (30 meters). Setup is simple and consists of installing a meter, installing EXAIR's wireless-to-Ethernet gateway and running the no-charge graphing software available from our website. 128 bit encryption is in place for secure wireless transmissions and they are configured to prevent unwanted joining upon the network.

 

Hot Tap 

This meter allows for installation under pressure, eliminating the need to isolate and remove pressure from the pipe it is being installed upon. It incorporates two valves that the probes pass through and a muffler that collects chips from the drilling process. It takes an equally short amount of installation time as the standard meters. Available on 2" and 50mm or larger flowmeters.

Pressure Sensing 

Digital Flowmeters monitor pressure and flow. A pressure sensor is mounted between the two flow sensing probes. The pressure signal is provided as a second milliamp output. The display can be configured to show pressure or flow. The pressure signal is also available through wired or wireless serial outputs. The pulse output is replaced with a transistor output configured as a low- pressure alarm when the pressure drops below 50 PSIG. Available on 2" and 50mm or larger flowmeters.

Digital Flowmeter with wireless capability

What is The Digital Flowmeter with wireless capability?

EXAIR's Digital Flowmeter with wireless capability is available as a built in option for EXAIR Digital Flowmeters. The easy way to monitor compressed air consumption and waste can now be done wirelessly over a ZigBee mesh network! A radio module within each meter transmits data to an Ethernet connected gateway. Using the ZigBee mesh network protocol, data can be passed from meter to meter to extend the distance over which the wireless system can operate. Each meter has a range of 100' (30 meters). Setup is simple and consists of installing a meter, installing EXAIR's wireless-toEthernet gateway and running the graphing software available from our website.

Why The Digital Flowmeter with wireless capability?

The Digital Flowmeter with wirelss capabilty includes a wireless output flowmeter and a wireless-to-Ethernet gateway for new installations. There are also available without a gateway if adding a meter to a gateway already existing in your plant. EXAIR simplifies the process by configuring each gateway to commuicate with the flowmeter(s) to provide the necessary communication for monitoring your system. Models from 1/2" to 4" iron pipe are in stock. Each Digital Flowmeter is calibrated for the pipe size which it is mounted. The large digital display shows air use in either SCFM or Cubic Meters per Hour.

Advantages:

• Provides wireless monitoring of EXAIR flowmeters throughout a plant
• Configured to prevent unwanted joining upon the network
• Monitoring software provided at no charge
• Utilizes mesh networking protocol to relay data from remote meters
• Transmits current air usage and cumulative air usage data
• 128 bit encryption for wireless transmissions
• Identify areas aith high compressed air use
• Models from 1/2" to 4" Schedule 40 iron pipe in stock
• Modesl are also available for 5" and 6" in iron pipe
• Models are available for sizes 3/4" to 4" in copper pipe
• Easy to install

Summing Remote Display

What is The Summing Remote Display?

EXAIR's Summing Remote Display for the Digital Flowmeter makes it easy to monitor compressed air consumption form a convenient location. With the push of button, the display cycles to show the current air consumption, usagefor the previous 24 hours, and total cumulative usage. Regular monitoring of the air usage of a machine, process or department makes it possible to save thousands of dollars per year in compressed air waste by indentifying the costly leaks or inefficient air products.

The Digital Flowmeter (sold separately) has a four digit LED display that directly indicates the SCFM (standard cubic feet per minute) or m3/hr (cubic meters per hour) of airflow through the pipe it is mounted upon. The Summing Remote Display shows that flow measurement, the daily and cumulative usage and is frequently used when the Digital Flowmeter is in an obscure, hard to read location. The accuracy of the displayed measurement is within 5% of the reading when the air temperature is 40-120ºF (4-49ºC) and air pressure is between 30-140 PSIG (2-10 BAR). No adjustments or calibration are ever required. The Summing Remote Display is CE and RoHS compliant. It is prewired with 50' (15.2m) of cable and is powered by the Digital Flowmeter.

 

USB Data Logger

What is The USB Data Logger?

EXAIR's award-winning Model 9147 USB Data Logger connects directly to your Digital Flowmeter and is simple to use. Download the software to configure the Data Logger to record your flow rate from once a second (about nine hours of data) up to every 12 hours (over two years).

When the Data Logger is removed from the Digital Flowmeter and plugged into a computer, the data can be viewed in the software or exported directly into Microsoft Excel. The Data Logger is  available pre-installed on the Digital Flowmeter.
