1 Warning - Read this first

Compressed gasses can be dangerous! Please familiarize yourself with the forces under pressurized conditions. Respect the local guidelines and regulations for working with pressurized equipment.

Gas flow through pipes follows certain physical laws. These physical laws have serious consequences for the installation requirements. Familiarize yourself with the basic physical laws of flow measurement, to make sure that the product is installed correctly. Always make sure that upstream length, downstream length, flow, pressure, temperature and humidity conditions are within specifications.

Precision instruments need maintenance. Check your flow meter regularly and make sure it remains clean. When polluted, gently clean the sensor using demineralised water or cleaning alcohol. Precision instruments need regular re-calibration. To keep your VPFlowScope probe in best shape, it needs recalibration. We advice annual recalibration.

Not intended for fiscal metering or billing. Our flow meters are not certified for fiscal metering. Laws on fiscal metering and billing may vary per country or state.

Do not overestimate the results. VPInstruments does not take any responsibility for the correctness of measurement results under field conditions. The practical measurement uncertainty of a flow meter in the field may

vary, depending on how well it is installed, due to the nature of gas flow. The piping table provides guidelines on how to optimize the field accuracy. Our products are not intended to be used as a single means to determine compressor capacity.

Do not open the device. Our instruments are assembled with high precision. Opening this device is dangerous and may destroy the instruments. Warranty is voided when you open the instrument.

Feedback leads to product improvement. Please share your experience with us, as we are continuously improving our products in our commitment to quality, reliability and ease of use. Let us know via sales@vpinstruments.com!

3 Product overview

The VPFlowScope in-line measures mass flow, temperature and pressure simultaneously. All these parameters are key to proper compressed gas measurement and are therefore included in all models. All data can be accessed by Modbus RTU, 4..20mA and pulse.

The VPFlowScope in-line is available in three configurations to fit every application. Use the connector cap for sensor features only, ideal for integration into a central management system. Use the display module for central read out and data logging. Use the VPFlowTerminal for central read out and data logging on location where a standard display can not be read out. For all models, all parameters and outputs are available.

The VPFlowScope in-line is available in three sizes: 0.5", 1" and 2". Additional options are available for all types:

3.1 Configuration

The instruments are pre programmed and ready to use. For configuration of the outputs and data logger, the VPStudio configuration software is used. This software can be downloaded from our website. www.vpinstruments.com/downloads

3.2 VPFlowScope in-line D0 (no display)

The D0 model can be used in applications where local read-out and data logging is not required. With it's various outputs the VPFlowScope in-line can be connected to remote data loggers.

3.3 VPFlowScope in-line D10 & D11 (display version)

The D10 and D11 models add a 3 row display with keypad to the VPFlowScope in-line. All parameters will be shown on the display in real time. The keypad can be used to start a data log session or to change the key parameters of the VPFlowScope in-line. The D11 model also features a 2 Million point data logger. All output parameters for remote connection remain available on the M12 connector.

3.4 VPFlowScope in-line D0 with the VPFlowTerminal

The VPFlowTerminal can be used as a remote display for situations where the local display can't be read. All display features will be available on the remote display. The VPFlowTerminal is equipped with a 10 m / 32.8 ft. cable with M12 8-pin connector. Therefore the D0 model needs to be ordered with an M12 8-pin connector. The VPFlowTerminal features a 2 Million point data logger which extends the data log capacity of your VPFlowScope in-line.

4 Quick start

This chapter contains the basic steps to start using your VPFlowScope in-line flow meter. Additional information on all subjects can be found in the next chapters.

1. Unpack

Unpack the meter and check if all items are there and in good shape. A checklist with all items is available on the box.

2. Mechanical installation

· Find the best point of installation for this product. Make sure that all specifications are met.

· For installation of the VPFlowScope in-line, the pipe needs to be cut. Mount the VPFlowScope in-

line between the pipe ends. Use tri-clamp or similar adapters for quick installation and removal.

· For installation with the tubing kit: The connection is BSP outer straight thread [For NPT thread, chase the BSP thread of the pipe ends with a die]; 0.5", 1" or 2" depending on the VPFlowScope in-line model.

· For installation without tubing kit: The connection is BSP inner straight thread [It can accept NPT male thread ends]; 0.5", 1" or 2" depending on the VPFlowScope in-line model.

See chapter mechanical installation for more detailed information.

3. Electrical installation

3.1 Permanent installation

Connect a cable with 5 Pin M12 connector to the VPFlowScope in-line. The cable can be connected to a central data acquisition / building management system or data logger via Modbus, 4..20mA or pulse. See chapter electrical connections for more information.

Apply 12-24 VDC to power up the device. Use a Class II power supply (less than 2 Amps). If the built-in display option is available, it will light up when power is applied.

3.2 Temporary installation

Use a 12 Volt power supply with M12 connector to power the VPFlowScope in-line. This quick method is ideal for audits.

4. Data recording

When the data logger is available a data log session can be started by pressing the esc button and then enter. All parameters will be logged with the default logging intervals. These logging intervals can be changed with the VPStudio software. This software tool is also used to retrieve the recorded sessions.

5 Measurement

For all parameters the update interval is 1 second. Within this second, multiple samples are taken and averaged to provide a stable and reliable output.

5.1 Flow

The VPFlowScope in-line uses our proprietary insertion type thermal mass flow sensor. There is no bypass flow, which results in a high robustness and less sensitivity for dirt or particles. The flow sensor is directly temperature compensated.

The sensor response signal is directly related to the mass flow rate and can be described by the following formula:

Vout = k *λ* ρ * v * (Ts-Tg)

Vout = output voltage k = sensor (geometrical) constant

λ = thermal conductivity of the gas ρ = density of the gas

v = actual velocity in m / sec Ts = sensor temperature Tg = gas temperature

The optional bi-directional sensitivity is shown in the picture on the right. In bi-directional mode the negative flow value will show up as a minus sign. The 4..20 mA value needs to be adapted to suit the application. See chapter 9.1 for details.

5.2 Pressure

The VPFlowScope in-line features a built-in gauge pressure sensor. The sensor range is 0...250 psi, rounded off this equals 0...16 bar gauge. The sensor cannot measure vacuum, please contact us if you have a vacuum application. The sensor membrane can handle media which are compatible with glass, silicon, stainless steel, Sn/Ni, plating and An/Ag solder.

The sensor signal is sampled with 16 bits. The practical resolution is 0.24 mbar on the 0..16 bar scale, which is equal to 0.004 psi on the 250 psi scale.

5.3 Temperature

The built in temperature sensor measures the compressed air/ gas temperature. It is mounted in a separate position, to ensure quick response time and low self-heating of the sensor element. The signal is sampled with 16 bits. The resolution is less than 0.1 °C. In a vertical pipe, with flow going down, the temperature sensor may heat up at zero flow conditions, due to the heated flow sensor element. This effect will disappear as soon as there is consumption.

For optimal measurement performance, the VPlowScope in-line needs to be in a stable temperature environment. When exposed to quick temperature changes or large temperature changes (for example taking the unit from outdoor to indoor during winter time, or when mounted downstream of a heat regenerated drier) the temperature compensation may lag behind, which may result in significant measurement errors.
