Manas Microsystems Private Limited

Manas have now introduced a new Ultrasonic BTU meter. Ultrasonic BTU meter works on the transit Time or Time of Flight priciple. The flow meter unit utilizes two trasducers that function as both Ultrasonic transmitter and receiver. The transucers are either clamped on or inserted to the outside surface of the closed pipes.

BTU 100 L is a versatile compact energy totalizer, extremely useful for measurement of energy consumed. It measures the thermal energy required for air conditioning. It accepts 3 inputs, each one from a flow meter for chilled water, inlet temperature sensor and the outlet temperature sensor. From this it calculates the thermal power and energy consumed in maintaining the temperature at given level.  

Advantages

• Compact Wall Mounting design with IP 67 Enclosure.
• Choice of Engg. Units : KW / MBTU
• Serial Interface with computer through MODBUS RTU / MODBUS IP.  

Features : 

• Sizes available for 1” to 24” [ DN25 -DN600 ]  
• The meter Contains No Moving parts and Fast response to flow transits.
• Highly Accurate and Reliable.
• Isolated 4-20 mA output Proportional to Flow Rate.
• No need to cut the pipe or stop water, easy Installation for Clamp on Type.  

Other Details:

• Manas has introduced heat energy transfer meter (HET) to measure thermal energy using various fluids which are being used as heat transfer medium
• Thermic fluid which acts as a heat carrier and circulated through the user equipment
• It transfers the heat to the process through the heat exchangers
• The instrument accepts signals from flow/DP transmiter
• Pressure transmitter (Two number) and temperature sensor/temperature transmitter (Two numbers) and gives the output in terms of 4-20mA which is proportional to heat power

 

Features:

• Data logging facility available
• Password protection on all programming modes (except display mode) to avoid wrong programming by an unauthorized person
• Suitable for thermic fluids like HYTHERM 500, HYTHERM 600, DOWTHERM A, DOWTHERM T etc.

 

Other Details:

• Manas make british thermal unit (BTU) calculator consists of pair of temperature sensor with integral energy computing capability unit to calculate net heat consumed
• Also used for HVAC applications

 

Net Heat= QM X (T1-T1)

where,

• QM: Flow rate of cooling medium
• T1: Inlet temperature
• T2: Outlet temperature

 

Specifications:

• 4-20 mA output proportional to power output.
• 16x2 LCD, 9 digits for total energy & 5 digits for instantaneous power.
• The engineering unit can be selected as either KW & KWHr or BTU/Hr & BTU.
• Communication port RS 232/485 is available with MODBUS RTU.

Main Features:

• Based on calculations of thermal power & energy consumed through measurement of flow, temperature difference of inlet & outlet of the medium.
• Password protection on all programming modes (except display mode) to avoid wrong programming by an unauthorized person
• Backup of totaliser on power failure in non-volatile memory
• Buzzer indication for faults/Error with blinking LED (Programmable)
