Product Name: Electromagnetic calorimeter Model MCM10A
Product Description
OVERVIEW: -
The Yamatake model MCM10A is a custody transfer meter used to measure the calorie consumption
of air conditioning systems in buildings or shopping malls or it can be used in
district heating/cooling applications. The flow rate is measured by an electromagnetic
magnetic flow meter having field proven Yamatake technologies. It measures the flow rate of chilled water/water with glycol/hot water and calculates calorie consumption with its two temperature inputs (supply and return).
ADVANTAGES: -
Reduced total cost of ownership:
No additional computing system for calorie consumption calculation is necessary.
Precise cooling/heating cost measurement:
Yamatake electromagnetic flow meter technology ensures accurate flow measurement.
Its temperature sensor compensation function provides accurate calorie consumption measurement.
Energy efficient:
No pressure loss occurs with the electromagnetic flow meter thus resulting in less energy required
for the flow.
FEATURES: -
• The Yamatake model MCM10A has a calorie consumption calculation program.
• It has two terminals for the temperature sensor (Pt 100 RTD sensor) input (supply and return).
• The device is provided with two types of output, analog (4 to 20mA) and pulse output (totalized value).
• The Yamatake model MCM10A accumulates the totalized values of calorie consumption for
both cooling and heating modes.
Applications: -
Buildings / Shopping malls:
Calorie consumption measurement for air conditioning systems
District heating/cooling:
Calorie consumption measurement
FUNCTIONAL SPECIFICATIONS: -

0 to 50°C
Ambient humidity limits:
5 to 85% RH (no condensation)
Company Details
The success of EASE led to questions about how well robots could build structures in space. The SSL's first neutral buoyancy robot, the Beam Assembly Teleoperator (BAT), was built in 1983 specifically to construct the EASE structure. Over BAT's... more
