The center provides organic food and luxury-hotel amenities, including a heated pool and turndown service. A Turbine Meter has a turndown ratio of 10&colon;1. Turndown service is offered by cabin crew upon request. A Thermal Mass Flow Meter has a turndown ratio of 1000&colon;1. Therefore the meter requires a turndown ratio of at least 10&colon;1. Multipath ultrasonic meters often have a stated turndown ratio of 50&colon;1. An orifice plate meter has a practical turndown ratio of 3&colon;1. This allows extreme turndown (low-flow) without significant pulsation. Diaphragm meters are considered to have a turndown ratio of 80&colon;1. However, typical turndown ratio is 5. Higher turndown ratios mean fewer stops and starts and hence fewer losses. On the way to and from court, a turndown collar and tie is worn. Positive displacement flowmeters are very accurate and have high turndown. Another variation is the "Turndown". The turndown in form placed significant pressure on Carlton's off-field organisation.
