Product Data Sheet

1 / 4

The flow meter is a handheld type with clamp-on

transducer which offers a variety of optional features. It is

designed to measure the fluid velocity of liquid within

closed conduit or pipe. The meter is compact and robust

which comprises additional functions that can turn it into

more than just a flow meter.

The meter utilizes two non-contacting and clamp-on type

transducers that function as both ultrasonic transmitters

and receivers. The transducers are clamped on the outside

of a closed pipe at a specific distance from each other.

The flow meter operates by alternately transmitting and

receiving a frequency modulated burst of sound energy

between the two transducers and measuring the time

interval that it takes for sound to travel between the two

transducers. The difference in the time interval measured

is directly related to the velocity of the liquid in the pipe.

The meter offers a heat quantity measurement function

that turns the instrument into a portable energy meter.

When equipped with this feature, the flow meter

Handheld Type Ultrasonic Flow Meter

MHC-3000H

Application

--pump testing and inspection

--inline flow meter performance verification

--leakage and blockage detection

--flow surveys

--cooling and heating fluid measurements

--deluge and extinguisher system testing

--demineralised water measurement

--clean room applications

Highlights

--heat measurement function optional

--various units to display

--great pipe range from 15 to 6000mm (1/2"~236")

--temperature range from -40 to 160℃ (-40°F~320°F)

--accuracy to ±1%

--light weight, no more than 600g (1.32lbs)

--easy installation and operation

--bi-directional flow measurement

incorporates measured flow and temperature values

delivered by two PT100 sensors into heat flow and heat

quantity. This is valuable information to assess the

efficiency of heat exchangers and HVAC systems.

The meter can be ordered with an internal data logger,

which is available to store up to 100,000 measurements

with each measurement which can be selected by the user

before each measurement. The data can be transferred via

RS485.

The meter can be successfully applied on a wide range of

metering applications. Pipe size ranges from 15 to

6000mm (1/2" to 236") and transducers working

temperature can be up to 160°C (320°F). A variety of

liquid application can be accommodated: ultrapure liquids,

potable water, chemicals, reclaimed water, cooling water,

river water, plant effluent, alcohol, etc. Because the

transducers are non-contacting and have no moving parts,

the flow meter is not affected by system pressure, fouling

or wear. Please consult the factory of assistance.

Optional Heat Measurement Function

The ultrasonic flow meter with optional heat flow module installed is designed to measure the rate and quantity of heat

delivered to a given building, area or heat exchanger. The meter measures the volumetric flow rate of the heat exchanger

liquid (water, water/glycol mixture, brine, etc.), the high temperature at the inlet pipe and the low temperature at the

outlet pipe. Heat delivery is calculated by the following equation.

Rate of heat delivery = Q*(Tin – Tout)*c

Where

Q = volumetric flow rate

Tin = high temperature at the inlet

Tout = low temperature at the outlet

C = specific heat of the liquid
