Applications
- The F-Series is your first and safest choice for field-mount indicators. Especially in harsh weather conditions like rain, snow, salty atmospheres and temperatures between -40° F up to 176° F (-40° C up to 80° C) for safe and hazardous area applications.
- Applications where net flow calculation at base conditions is desired without the influence of thermal product expansion.
- Liquid flow measurement with mechanical flowmeters where a precise calculation over the full measurement range is required. Also, continuous flow rate monitoring is required.
- For batching small up to very large quantities. Single or repeating batches.
- Fuel consumption calculation for diesel engines on board of ships or trains. Sum function: where flows are split-up in two pipelines and total flow has to be calculated.
