MASTERING LIQUID METERING: OVERCOMING THE CHALLENGES OF PRECISION BATCHING
M 12
Titan Enterprises shares key insights to help engineers and operators navigate challenges of precision batching to ensure accurate measurements and smooth process operations.
etering batches of liquids may seem straightforward at first glance – install a flowmeter in the product line, connect it to an instrument, control the
measurement with on-board software, wire in a valve, enter your required volume, press a button and the right amount of liquid is dispensed into your vessel. However, real-world applications reveal a host of complexities that must be addressed to achieve precise and repeatable results. Today’s advanced process and liquid handling systems demand highly precise flow measurement. From adding water to food production mixers, dispensing flavourings to beer or cider at point of sale, to handling aggressive chemicals, even slight inconsistencies in system design can lead to inaccuracies, wasted product, or disrupted processes. For batching systems, the critical factor is repeatability – ensuring the required volume is delivered consistently every time. To achieve
this, ideally the system should maintain consistent process conditions, however, this is not always feasible. For instance, temperature fluctuations throughout the day can alter fluid viscosity and volumetric flow measurements. Similarly, a decrease in the feed liquid tank level supplying the process pump can reduce the dispensing rate, impacting the accuracy of the flow meter and the flow control valve. Therefore, as a starting point, batching system designs should aim to minimise as many variables as possible within a reasonable cost. Once this foundation is established, equipment such as flow meters, pumps, and valves can be selected to effectively compensate for any parameter variations.
Titan’s NSF-Approved Beverage Flowmeter is designed specifically as a flow measurement solution for the drink dispensing market. With its exceptional repeatability, this low-cost device is installed around the world enabling industries to unlock higher yields, whether in beverage processing equipment or a bar tap wall in a restaurant.
APPLICATIONS OF LIQUID FLOW MEASUREMENT AND CONTROL IN BATCH PROCESSES
Batching ingredients in juice processing Fruit juice production relies on accurate flow measurement of small quantities of ingredients to maintain product quality. Liquid flow meters monitor and control the dispense of water, flavourings, sweeteners, and other ingredients, ensuring the right proportions for optimal flavour and shelf life. High-precision flowmeters provide repeatable measurements, indispensable for maintaining product consistency.
Liquid batch dispensing in beer walls Incorporated as part of an installed beer wall, the valves and flowmeters count and control the dispensing of beer at the bar taps. Titan’s low-cost NSF-Approved beverage turbine meters are used by long-term American customer, a self-pour technology company, in their self-pour beverage walls, to accurately measure and control dispensed beer at self-serve counters.
