2.2 WORKING PRINCIPLE
The SGM-101F is composed by a digital converter and two clamp-on or insertion type ultrasonic transducers.
The instrument calculates the instantaneous flow rate value by measuring the flight time difference of the ultrasonic pulses.
- Compact system for conductive and non-conductive fluids, even with the suspended material presence (<10g/l; <Ø1mm)
- Measuring ranges from <0,2m3/h to >30000m3/h
- Applicable to various pipes materials (eg. SS316, copper, plastic, etc.), with or without an inner lining.
- Power supply 24Vac; 115Vac; 230Vac.
The meter is designed to measure the fluid velocity inside a pipe.
The clamp-on transducers models allow an easy installation.
The transit time flow meter uses two ultrasonic transducers that work as transmitters and receivers.
They are installed externally to the pipe at a specific distance from each other.
They can be installed at V mode (2 sonic section), at W mode (4 sonic section) or at Z mode (1 sonic section).
The installation method choice depends on the pipe and the fluid characteristics.
The SGM-101F measures the transit time via the two transducers that alternatively transmit and receive a sound pulses
sequence.
The difference in the measured transit time is directly related to the fluid velocity in the pipe.
θ= sonic section angle
D = pipe internal diameter
T1 = sound transit time from the upstream transducer to the transducer downstream
T2 = sound transit time from the downstream transducer to the transducer upstream
∆T = T2-T1

5-PIPE SPECIFICATIONS
5.1 OUTSIDE PIPE DIAMETER
In the event that an appropriate instrument to measure the pipe outer diameter is not available
(programming in M11), proceed as follows:
- use a rope or paper tape or sheet
- wrap the pipe with rope or paper tape or sheet and mark the circumference point
- measure the length corresponding to the pipe circumference
- enter the measured value to “Pipe Outer Perimeter” menu (M10), SGM-101F will automatically calculate
the correct pipe diameter value
5.2 PIPE THICKNESS
Value measured on site using an appropriate tool (caliper, ecc.), or from the technical data of the hydraulic
circuit (programming in M12). In the presence of tubes without inner lining, is possible to use the SGM-100T thi-
ckness gauge.
5.3 PIPE MATERIAL
Value detectable on site, or from the technical data of the hydraulic circuit (programming in M14).
5.4 INNER LINING MATERIAL
Value detectable on site, or from the technical data of the hydraulic circuit (programming in M15).
5.5 INNER LINING THICKNESS
Value measured on site using an appropriate tool (caliper, ecc.), or from the technical data of the hydraulic
circuit (programming in M16).
