ST505 Stationary Ultrasonic Energy Meter
Integrate into your management system to provide remote measurement
services.
Product Information
ST505 is a high-accuracy ultrasonic energy meter with clamp-on
transducers measuring big pipe diameter, which is built-in RTD
module. When it is equipped with PT100 temperature sensor, ST505
can be upgraded into energy meter used for measuring individual
energy consumption in any liquid heating/cooling systems. The meter
is supplied complete with flowmeter and temperature sensor, which
can makes the system real-time detect the temperature of supply and
return pipe.
The energy meter can be widely applied in various applications,
like HVAC, cooling tower, data center, energy audit, and
building(shipping mall, office, museum, hospital, school, subway
etc.). Energy meter, also called thermal energy meter or heat
meter, is used to accurately measure heat consumption in heating
and cooling facilities so as to reach energy-saving and
cost-saving.
ST505 is a brand-new high-end product that is made of aluminum
alloy material and realizes CNC processing method. It adopts the
industry-leading full-sealed iron-absorbing side-opening technology
without any screw locking, and the tedious steps of screwing are
reduced. Such a convenient design truly realizes "one-second
opening".
◆ Benefits
- Measure the actual flow and total consumption of various liquids.
- No loss of process control, optimization of assets and efficiency, no
downtime or expense from calibration.
- Adaptive signal processing algorithms optimize performance,
ensuring accurate measurements even in challenging flow conditions.
- Clear display interface and LCD display with alarm function, easy
to operate and debug
- Utilize transit-time ultrasonic technology so as to realize
bi-directional flow measurement by precisely measuring the time it takes for ultrasonic signals to transmit upstream and
downstream.
- Leverage the data logging capabilities to analyze historical flow
patterns to make system optimization.
- Built-in keypad and simple menu system for fast and easy
programming of pipe diameter, pipe material, liquid type, and
measurement nuits.

Installation
◆ V Method
The "V" method is considered as the standard method. It usually
gives more accurate reading and is used on pipe diameters ranging
from 25mm to 400mm(1'' ~ 16'') approximately. Also, it's convenient
to use, but still requires proper installation of the transducer,
contact on the pipe at the pipe's centerline and equal spacing on
either side of the centerline.
◆ Z Method
The signal transmitted in a "Z" method installation has less
attenuation than a signal transmitter with the "V" method. This is
because the "Z" method utilizes a directly transmitted(rather than
reflected) signal which transverses the liquid only once. The "Z"
method is able to measure on pipe diameters ranging from 100mm to
3000mm(4”~120”).
◆ N Method
With the "N" method, the sound waves transverse the fluid twice and
bounce three times off the pipe walls. It's suitable for small pipe
diameter measurement. The measurement accuracy can be improved by
extending the transit distance with the "N" method(uncommonly
used).
◆ W Method
As with the "N", the measurement accuracy can also be improved by
extending the transit distance with the "W" method. The sound wave
transverse the fluid four times and bounces four times off the pipe
walls. It's suitable for very small pipe(diameter is less than
50mm/2'').
