**F018 Flow rate Monitor / Totalizer - with linearization, pulse, alarm and analog outputs + HART communication**

The F018 is a local indicator / totaliser with linearization, which displays the actual flow rate, the resettable total and the non-resettable accumulated total. The F-series is known worldwide as a series of user-friendly indicators. The F018 is even more impressive. With HART communication you can easily communicate with smart "DD enabled host" systems.

Application: Flow monitoring with an accurate calculation over the entire measuring range, requiring re-sending of the totalizer and monitoring of the flow function and HART communication.

**F114 Ratio Monitor / Totaliser - with high / low alarms and analog outputs**

The F114 flow computer calculates the actual ratio between two separate flows. It offers the possibility to set a low value and a high alarm value ratio. Special precautions are taken to allow start-up problems and incorrect ratio values during a certain period. Based on the location of the flow meter, a selection can be made from six different formulas.

Application: Mixing or mixing of two components where continuous display, monitoring and totalization of the ratio is important. For example in construction, roof or wall insulation, adhesives and coating.

**F115 Bi-directional flow indicator / totalizer - with analogue, pulse signal and flow direction outputs ** The F115 has been developed for applications where flow direction is a problem. It is required to provide two pulse signals from the flow meter that are 90 ° or 270 ° degrees out of phase. In the case of a reverse current, the current velocity is displayed as a negative value, the totalizers count down and a switching output is set. The pulse and analog outputs reflect both current directions. On-screen engineering units can be easily configured from an extensive selection.

Application: Bi-directional flow measurement applications can be found by loading and unloading ships where a bi-directional flow meter is used. Another application is the backflow correction due to shocks in a pipeline caused by piston pumps or valve behavior.

**F116 Ratio Monitor / Totaliser - with high / low alarms and analog outputs**

The F116 power computer has been developed to calculate the difference / consumption or the total volume. The usual problems that arise with such applications are: pulsating currents, very low consumption values, vibrations and high ambient temperatures. These are all well cared for in the design and operation of the F116. The pulse and analog outputs reflect the calculated difference or the sum value.

Application: Differential function: calculation of fuel consumption for diesel engines on board ships or locomotives. Sum function: where flows are split into two pipelines and the total flow must be calculated.

**F118 Flow rate monitor / totalizer - with linearization, high / low alarm, analog and pulse outputs**

The F118 is a versatile flow indicator / transmitter and totalizer with the ability to accurately linearize the flow meter signal. In addition to the average K-factor or span, ten linearization points can be entered with their frequencies or values. The unit interpolates between these points, significantly improving accuracy in each current range, even for very low frequency applications. In addition, a continuous flow monitoring function is available with high and low flow alarm values and a maximum of three alarm outputs.

Application: Liquid flow measurement with mechanical flow meters where accurate calculation over the entire measuring range and continuous flow speed monitoring is required.

**F126EG Flow computer - with temperature and pressure compensation for corrected gas volume**

The F126-EG flow computer has been developed to calculate the corrected gas volume under normal circumstances. The corrected volume flow is calculated by measuring the uncorrected volume flow, actual line temperature and pressure that are processed with the equations stored in the flow computer. A compressibility factor can be set to approximate a real gas behavior. The reference conditions can be defined as desired (e.g. 15 ° C or 60 ° F and 1,013 bar).

Application: applications where mains current calculation of gases is required under normal conditions without the influence of thermal product expansion and pressure.

**F126EL Flow computer - with temperature compensation for corrected fluid volume**

The F126-EL flow computer has been developed to calculate the corrected liquid volume under normal conditions. The corrected volume flow is calculated by measuring the uncorrected volume flow and the actual line temperature that is processed with the thermal expansion coefficient algorithm stored in the flow computer. The reference temperature can be defined as desired (for example 15 ° C, 20 ° C or 60 ° F).

Application: applications where net flow calculation of liquids is desirable under normal conditions without the influence of thermal product expansion.

**F127 Differential flow computer - with temperature compensation for corrected fluid volume**

The F127 flow computer has been developed to calculate the corrected differential fluid volume under normal conditions. This is calculated by measuring the unadjusted volume flow and the actual line temperature in both the supply and return lines. These signals are processed with the thermal expansion coefficient algorithm stored in the flow computer. The reference temperature can be defined as desired (for example 15 ° C, 20 ° C or 60 ° F). The usual problems that arise with such applications are: pulsating currents, very low consumption values, vibrations and high ambient temperatures. These are all well cared for in the design and operation of the F127.

Application: Calculation of the net fuel consumption for diesel engines on board ships or locomotives, generators or burners, corrected for the influence of thermal product expansion
