Portable Flowmeter

 Water monitoring with a portable instrument


The portable flowmeter is the ideal solution for measure different parameters related to water as flow.

It is an instrument very appropiate to applications of the overead pipeline and underground pipeline.

This flowmeter uses a non-invasive method to take the measurements. It is efficient and it hasn’t moving parts.

DFTP1 Portable Transit Time Ultrasonic Flow and Heat Meter is a new product of SmartyPlanet released in 2013. It provides for precise and reliable ultrasonic clamp-on flow and heat measuring as other conventional portable transit-time products. Furthermore it has the advantages of wireless remote handheld operator function, panel USB data port and optional function of energy meters, can be used as a powerful portable energy flow meter.
The rechargeable battery can work over 50 hour, also can work with 110VAC/220VAC power supply for long time field monitoring.
Wireless handheld operator can be used to operate meters replacing the panel keyboard and read data remotely, the distance of transmission can up to 100m with no obstructions. It is more convenient for the applications of the overead pipeline and underground pipeline.
The meter provides multiple outputs: Data storage function, 4~20mA, Frequency (For Flow rate or Total flow), Relay (For Total flow or Alarm), RS485 (Modbus-RTU) output, wireless handheld operator and GPRS.
