VP Instruments Air Compressor Monitoring Equipment

Countless industrial applications worldwide rely on compressed air systems for their operations and productions. However, these systems are notorious for leaks and energy waste that can drive up operational costs and burn through resources.

Since 1999, VP Instruments has developed innovative, easy-to-use measurement tools to help businesses identify inefficiencies and work to address these issues.

VP Instruments compressed air flow meters offer insight into consumption, actionable data and ample opportunities to optimize your compressed air and industrial gas systems.

VPFlowScope Flow Meters

The VPFlowScope line of flow meters for compressed air and industrial gases features four-in-one simultaneous measurement parameters — thermal mass flow, pressure, temperature and total flow. Together, these metrics give users a complete picture of their compressed air system’s functions and consumption.

VP Instruments Air Compressor Monitoring Equipment VPFlowScope In-line 3:8

VPFlowScope meters are able to measure air, nitrogen, oxygen, helium, argon and other noncorrosive industrial gases bidirectionally for the most accurate data available.

At The Titus Company, we offer the entire line of VPFlowScope products, including in-line and insertion type flow meters to help you find solutions to any measurement problem.

In-Line Flow Meters

In-line flow meters are installed directly in-line to gather and provide all of the data you need to analyze and optimize your compressed air system. These types of flow meters are ideal for pipes no more than 2 inches in diameter. For larger pipes, you should use an insertion flow meter.

VPFlowScope In-Line 3/8-Inch Flow Meter

The VPFlowScope in-line 3/8-inch flow meter offers the perfect solution for measuring low flows of compressed air, oxygen and nitrogen up to 50 liters per minute (LPM). This meter features patented Thermabridge technology that allows for accurate readings of clean, dry gas and air.

VPFlowScope in-line 3/8-inch meters have built-in two-line TFT displays that show actual and total flow information about your compressed air system in real time. Modbus and analog outputs allow you to connect your meter with the VPVision interface and other monitoring systems for data analysis and collection.

Applications for VPFlowScope in-line 3/8-inch flow meters include:

  • Leakage measurements.
  • Cost allocation and measuring distribution networks.
  • Consumption measurements.
  • Oxygen and nitrogen generator output measurements.
  • Point-of-use measurements in compressed air systems.

VPflowScope In-Line Flow Meter

VPFlowScope in-line flow meters are ideal for point-of-use consumption measurements. They measure the flow, temperature, pressure and total flow of air and noncorrosive gases simultaneously and bidirectionally using patented Thermabridge technology.

These unique flow meters are designed specifically for in-line use on pipes with diameters of 2 inches or less.

VPFlowScope in-line flow meters give users all the data they need to monitor and manage their compressed air system. Other applications for these meters include:

  • Leakage management.
  • Energy consumption monitoring.
  • Cost allocation.
  • Submetering of compressed air.
  • Monitoring and submetering industrial gas flow.
  • Condition monitoring for pneumatic equipment.

Insertion Flow Meters

Insertion type flow meters are inserted into your pipes to calculate flow based on measurements at a single point.

VPFlowScope insertion flow meters can be installed under pressure, which means you won’t have any downtime for installation. Keep your system running and carefully install your meter probe for readings.

VPFlowScope M Flow Meter

VPFlowScope M flow meters are ultra-compact and lightweight for easy portability and installation. These innovative flow meters feature an ethernet interface, making them 4.0/IOT ready. You can connect directly to any network seamlessly for automatic access.

Users can also configure the system and download data log files using the USB interface or traditional Modbus and analog outputs.

However you choose to access your data, know that it will be reliable and consistent. VPFlowScope M flow meter does not require complicated calibration or extensive downtime. Instead, simply replace your system’s VPSensorCartridge and get back to work.

VPFlowScope M flow meters are useful for a number of applications, including:

  • Air audits.
  • Submetering of compressed air and gases.
  • Ring networks.
  • Leak detection.
  • Demand-side compressed air and industrial gas monitoring.
  • Cost allocation.

VPFlowScope DP Flow Meter

VPFlowScope DP is designed for measuring hot, wet, dirty compressed air and gases. This differential pressure flow sensor allows you to measure bidirectional flow, temperature, pressure and total flow simultaneously to monitor your system’s performance and efficiency.

VP Instruments Air Compressor Monitoring Equipment VPFlowScope DP flow meter

Unlike most other flow meter systems, the VPFlowScope DP flow meter can be used in compressed air and gas environments when the air has not been dried. They can be used for supply-side measurements right out of your compressor.

VPFlowScope DP flow meters are intended for use in high-velocity applications with continuous flow. Other applications include:

  • Compressor performance and efficiency measurements.
  • High-temperature measurements.
  • Demand-side flow measurement when dryers are not in use.
  • Supply-side audits.
  • Input and output monitoring for desiccant dryers and other air treatment equipment.

Differential pressure flow sensors like VPFlowScope DP should not be used for leak monitoring.

VPFlowScope Probe Flow Meter

The VPFlowScope Probe flow meter is the number one option for compressed air audits and fixed installations to measure dry, compressed air and other industrial gases. It can be used in various pipe diameters for both supply- and demand-side measurements.

VPFlowScope Probe flow meters are well-suited for the following applications:

  • Air audits
  • Submetering of compressed air
  • Demand-side compressed air and industrial gas monitoring
  • Cost allocation
  • Leak detection
  • Ring networks

VPFlowScope M Kit

The VPFlowScope M kit provides everything you need to get started measuring bidirectional flow, pressure, temperature and total flow simultaneously with the VPFlowScope M insertion type flow meter.
