Flow Product Application Notes
Steam Mass Flow vs. Volumetric Flow
Most flow measurement devices measure the velocity of the flow stream and use the pipe
dimensions in order to infer volumetric flow. A velocity based device cannot correct for changes
in density that are caused by pressure and temperature changes. This means that if the velocity
(inferred volumetric flow) remains constant but the density of the steam changes the flow meter
output will not change.
The customer will be paying the same amount for less energy.
By measuring pressure, temperature and flow and using a SuperTROL-II to perform the mass
calculation and compensation function any change in the properties of the flow stream will be
The customer is therefore billed only for the energy that is used.

The SUPERtrol utilizes the pressure and temperature signals as an entry point to its internally held steam tables, the density of the steam is then computed. The signal from the Vortex meter, which is proportional to volumetric steam flow, is then multiplied by the density in order to yield the mass flow of steam.

Pulse Signal K-factors
All pulse output type flow meters when they are dispatched by their manufacturer will have a
calibration certificate. The calibration certificate will show that the meter has been calibrated
over its flow range and noted on the certificate will be the average K-factor for the meter.
This K-factor will be given in terms of the number of pulses produced by the meter for a given
volumetric flow. (e.g.) 200 pulses per U.S. gallon, 150 pulses per liter etc.
This K-factor is the value that is entered into a batch meter or indicator/totalizer in order to give
a readout in engineering units.

- Hayes compatible modem connected to Intellect 69
- RS232 cable to attach the modem to Intellect 69
- Modem and communications software for your PC
The Intellect 69 RS232 interface is a simple 3 wire communication system, pins 2 and 3 carry data and pin 7 is the signal ground. Modems usually require some additional hardware handshaking signals therefore jumpers may have to be added to some of the modem inputs in order to make it fully compatible with the Intellect 69.

One of the most confusing aspects of instrumentation is the statement of accuracy, whether it be for a flow meter or for a calculation device.
We commonly see statements such as, “accuracy ±0.5%,” what we should really be talking about is a measurement uncertainty of ±0.5% or an accuracy of 99.5%.
The statement of a measurement uncertainty for a flow meter may be given as ±0.5%, but what is it 0.5% of, and over what range? Any given flow meter is prevented, for reasons of sensitivity or by the limitations of the physical phenomenon that makes it operate, from reading down to a flow of zero.
Hazardous locations are classified according to the hazardous materials present.
- Class I locations are those in which flammable gasses or vapors are present.
- Class II locations are those in which combustible dust is present
- Class III locations are those in which combustible fibers are present
