Description

Ultrasonic flowmeter is a kind of flowmeter developed based on the principle that the propagation velocity of ultrasonic wave in the flowing medium is equal to the vector sum of the average velocity of the measured medium and the velocity of sound wave in the stationary medium. It is mainly composed of a transducer and a transducer.

KACISE KUHM2100 series ultrasonic water meter adopts the most advanced non-magnetic technology, which has the advantages of high precision, stable operation, easy maintenance, strong corrosion resistance, long service life, beautiful appearance, safety and affordable.

Can be widely used in industrial process measurement and control, instead of mechanical flowmeter to improve the accuracy and reliability of measurement, instead of all kinds of high performance flowmeter.

It is widely used in the heat system with concentrated heat supplying management, separate household data collecting management.
Varies of communication modes are optional according to the users’ need.

Installation and Attentions

The heat meter both can be installed in Inflow pipe or Return flow pipe (factory default installed in the inflow pipe, if need to install on the return pipe, must be clearly indication before the factory during the production). When installation, should pay attention to the flow direction of medium is as the same as the arrow on the heat meter pipe body.

Special note: no matter the heat meter installed on inflow pipe or return flow pipe, the temperature sensor should be properly connected ( red label for inflow pipe, blue label for return pipe)

Instrument Common Problem

The meter cannot work normally

Heating system is working or not;

Globe valve is opened entirely or not;

the pipe is blocked or not;

the lead seal is complete or not;

Battery is good or not;

heat meter isn’t counting

①, heat meter reversed installation

②, transducer cables are broken

③, the filter is be blocked on heat supply pipe of in the resident room

How to determine the filter whether block?

Inflow temp. is normal, return flow temp. is too low, the temp. difference of inflow and return flow is more than 10°, flow rate is too low(m3/h), or now flow rate, usually the filter is blockage, or user does not use.

Solution:Close the valve (inflow and return flow valve), remove the filter, to observe whether filter is black, clean filter and inside of it, then install the filter, open pipe valves, wait 3 mins to check whether the flow rate and temp. is normal.

Heat meter data abnormal or jumping

①, Installation position is not correct, down water level

②, Front and back straight pipes are too short, bend is too big, front pipe diameter is

changing bigger.

Heat meter has flow quantity, no heat, or heat is very big

①, Without heat is usually reversed installation of inflow and return flow temp. sensors

②, Heat is very big, because the temp. sensor measure temp. incorrectly, temp. difference is very big.

Heat meter abnormal temp., or the temp. is 0

①, the temp. sensor cable is broken

②, Temp. sensor stainless steel casing is broken.
