OVERVIEW
Introduction
The flow computer Model F127 has been developed to calculate corrected differential liquid volume at normal conditions for generic products. A typical application is the measurement of fuel consumption by engines for power generators, e.g. on board ships and locomotives. The usual difficulties encountered in such applications include: pulsating flows, very low consumption readings, vibration and high ambient temperatures. These are all well catered for in the design and operation of the F127. The corrected volumetric flow in each line is calculated using the thermal expansion coefficient algorithm stored in the flow computer. The reference temperature can be defined as desired, e.g. 15°C, 20°C or 60°F.
Display
The display has large 17mm (0.67”) and 8mm (0.31”) digits which can be set to show flow rate, total and temperature. On-screen engineering units are easily configured from a comprehensive selection. The accumulated total can register up to 11 digits and is backed-up in EEPROM memory every minute.
Configuration
All configuration settings are accessed via a simple operator menu which can be pass-code protected. Each setting is clearly indicated with an alphanumerical description, therefore avoiding confusing abbreviations and baffling codes. Once familiar with one F-series product, you will be able to program all models in the series without a manual. All settings are safely stored in EEPROM memory in the event of sudden power failure.
Analog Output Signal
The calculated consumption (flow rate) is re-transmitted with the (0)4-20mA or 0 - 10V DC output signal. The output signal is updated ten times per second with a filter function being available to smoothen out the signal if desired. The output value is user defined in relation to the flow rate, e.g. 4mA equals to 15L/Hr and 20mA equals to 2000L/Hr. The output signal can be passive, active or isolated where the passive output type will loop power the F127 as well.
Signal Input
The flow computer measures the uncorrected volumetric flow and temperature in both supply and return line. The F127 will accept most pulse input signals for flow. For the temperature measurement, 2 or 3 wire PT100 elements or sensors with a (0)4-20mA / 0 - 10V DC output signal can be used.
Communication
All process data and settings can be read and modified manually or through the Modbus communication link (RS232 / RS485). Full Modbus functionality remains available for the Intrinsically Safe version (TTL).
Hazardous area
For hazardous area applications, this model has been ATEX certified Intrinsically Safe II 1 GD EEx ia IIB / IIC T4 T100°C with an allowed operational temperature of -30°C to +70°C (-22°F to +158°F). A flame proof enclosure is also available with the rating II 2 GD EEx d IIB T5.
Enclosures
Various types of enclosures can be selected, all ATEX approved. As standard the F127 is supplied in a GRP panel mount enclosure, which can be converted to an IP67 / NEMA 4X GRP field mount enclosure by the addition of a back case. Most popular is our rugged aluminum field mount enclosure with IP67 / NEMA 4X rating. Both European or U.S. cable gland entry threads are available.

To aid in the construction of a Fluidwell model number a model configurator must be used. The path to this Configurator is contained in the link shown below. However, it would help to first review the options shown below.
NOTE: If you require the product to be Intrinsically Safe (ATEX, IECEx, CSA or c-us), the options you choose should only include those options that carry the ATEX symbol next to them. The Configurator will not allow you to mix and match options, unless the product is to be used in a Safe Area.
Once a new model is generated using the Configurator, you will
- see the price of the fully configured model
- have an opportunity to purchase the product
- have the capability to e-mail the configuration to us, yourself, or a third person
