SOFTWARE DESCRIPTION
HART DD FILES The HART protocol enables two-way digital communication over the same wires as the 4-20mA analog signal without disturbing the 4-20mA signal. The bi-directional communication provides digital data access between field instruments and host systems. A host can be any software application from a technician’s hand-held device or laptop to a plant’s process control, asset management, safety or other system using any control platform. The HART Device Description (DD) file describes specific features and functions of a device.

PROFIBUS GSD FILES A PROFIBUS GSD file (General Station Description) provides a way for a configuration tool to automatically get the device characteristics of PROFIBUS instrument.

USB DRIVER The Windows USB driver allows communication from a B-Series device to a computer via a USB cable. B-Series devices include the 454FTB, 454FTB-WGF, 504FTB, 534FTB,and K-BAR 2000B product lines. Depending on the Windows operating system, internet access, and the Kurz device, the necessary USB driver might be downloaded and installed automatically. The barcode ID on the B-Series device sensor control board determines the correct USB driver. The barcode ID is located in the device menu (Display mode, option 33), in the configuration file (in the Electronic Board Barcode field), and on a label on the sensor control board. If the barcode ID is C51938 or higher, use the FTDI USB driver.

The FTDI USB driver is a 64-bit compatible virtual COM port (VCP) driver available on the FTDI Chip website (ftdichip.com) or you can click the link below. Kurz devices that use the FTDI driver started shipping in 2012.

Frequently Asked Questions

Thermal mass devices operate on the principle that a flowing gas cools a heated body. There are two type of thermal mass flow technology:

Constant Temperature Anemometers (CTA) heat the reference sensor to a fixed temperature and use the process sensor to monitor the flow temperature. Mass flow is determined based on the amount of electrical current used to maintain a constant temperature differential between the two sensors. The advantage of CTA meters is that the flow signal remains the same at all mass flow rates.

Constant Power Anemometers (CPA) heat the reference sensor with constant fixed current and use the process sensor to monitor the flow temperature. Mass flow is determined based on the temperature difference between the reference sensor and the process sensor. The disadvantage of CPA meters is that the flow signal decreases with increasing mass flow rate.
Thermal flow meters are designed to measure the mass of gas flows in pipes, ducts, vents, and stacks for dry or wet gas processes. All thermal flow meters indicate velocities referenced to a set of standard conditions. Kurz Instruments standard conditions are defined as 25°C at 101.325 kPa.

Standard (or Mass) Velocity is the velocity that a mass of gas would be moving if the temperature and pressure were at standard conditions. Standard Velocity is in units of standard feet per minute (SFPM) or standard meters per second (SMPS).

Standard Velocity: Vs = ρ v / ρ s

Where: ρ = actual gas density
v = actual gas velocity
ρs = standard gas density

Sometimes it is necessary to derive actual velocity from standard velocity. Actual Velocity is the velocity a “particle of dust” would be traveling if it were in a gas stream. When using actual velocity you will not know the mass or rather how many dust particles are moving in the gas stream. Actual Velocity is in units of feet per minute (FPM) or meters per second (m/s).

Where: Va= actual gas velocity
Vs = standard gas velocity
Pa = actual pressure in absolute units
Ps = standard pressure in absolute units
Ta = actual temperature in absolute units (degrees Kelvin or Rankin)
Ts = standard temperature in absolute units (degrees Kelvin or Rankin)
Enclosure heads are configured based on the initial order and are not intended to be rotated. Contact Kurz Customer Support for information about rotating the enclosure head.
Thermal mass flow meters are designed to measure the dry gas flow in pipes, ducts, vents, stacks, and flares in industrial and commercial processes. Industries include petroleum & petrochemicals, pulp & paper mills, wastewater, nuclear, landfills, semiconductors, and cement. The environments and applications include coal power generation, incinerators, continuous emissions monitoring systems, bulk powder drying, combustion air, recirculation air, and boilers.
Until the commercialization of the Kurz wet gas flow metering line (WGF), the answer to this question was no. All thermal flow meters prior to this advent are affected by liquid water which robs heat from the heated sensor and results in erroneous flow errors. Only the Kurz WGF successfully operates in a condensing gas environment.
Kurz thermal mass flow meters are temperature compensated to account for changing temperatures in the gas stream. Without temperature compensation, a thermal flow meter is affected by changing temperatures because temperature affects the heat transfer properties of a gas.
The thermal properties of a gas determine how fast or slow heat is pulled away from the heat source. Calibrating the heated sensor to a specific gas or gas composition allows a thermal sensor to accurately determine the flow rate. Operating a thermal meter outside its calibrated range can result in uncertain measurements.
If used correctly a Kurz flow meter does not need to be recalibrated. The sensing element should be periodically inspected (based on the process environment) to be free and clean of debris, as buildup can affect calibration. Once the sensor is cleaned, the meter will be back in calibration.

Kurz Instruments Thermal Flow Meter Calibration Policy
After sale meter calibration is not required provided the meter has been operated within its design specification and the sensors are clean, free from corrosion, erosion, or other physical damage.

The sensor and electronics do not drift when used within these limits. However, verification of the meters calibration is sometimes desired by the end user. Some popular calibration verification options are zero flow air testing, insitu-field calibrations, and laboratory flow tests. All of these calibration options are available from Kurz Instruments or third-party service providers.

Download Calibration Policy
The file provides instructions for building a Zero Flow calibration chamber and using the chamber to confirm that a flow meter is still within 3% of its original calibration.

Download Calibration Instructions
A laboratory calibration uses the same gas for calibration as where the meter will be installed. A laboratory calibration is performed by characterizing the instrument’s response to the flow of a specific gas of choice.

A correlation calibration begins by characterizing the instrument’s response to flowing air and then using a proprietary algorithm, the air response data is adjusted to the specific gas of choice.

A laboratory calibration is more accurate than a correlation calibration, but a correlation calibration is more economical.
There is no maintenance required other than periodically checking the sensor for particulate buildup. The process environment determines the maintenance schedule. Noncorrosive, particulate-free flows require less frequent checking than flows that have particulates or corrosive gases
There are 2-wire and 4-wire modules (or meters) that connect to a controller. The looped-powered, 2-wire module uses a single pair of wires to power both the 4-20mA signal and module via the controller’s 24v power supply. The self-powered 4-20 mA loop for a 4-wire module is externally powered and configured to power the 4-20 mA loop too. This self-powered 4-20 mA configuration will source the current or drive the current to a load sensing resistor in the controller.
The meter itself is not loop-powered however the 4-20 mA output signals can be wired as a loop powered signal (see below). The meter is a 4 wire device requiring auxiliary power (many watts) beyond the 4-20 mA current loop capability to operate the meter. The auxiliary power can be 24 VDC or 85-265 VAC.
The Kurz thermal mass flow instrument supports either self-powered or loop-powered circuits with a simple field wiring arrangement. The meters 4-20 mA output signal circuit can be powered either by the meter or by the customer’s control system.

If the signal circuit is powered by the meter then it would be considered a “self-powered” signal loop.

If the signal circuit is powered by the customer’s control system then it would be considered a loop-powered signal loop.
