Lanry Instruments Transit Time Principle Clamp-on Fixed or Wall mounted Ultrasonic Flow ( Heat ) ...
Lanry fixed ultrasonic transit time flow meters is capable of meeting accuracies of +/- 0.5% and +/- 1%of the true flow rate for lab. Lanry transit time ultrasonic flow and energy measurement paired PT1000 temperature sensors to monitor supply and return temperatures, commonly used in heating an...Read more -
Clamp on ultrasonic flow meter-Question 1
Lanry clamp on ultrasonic flow meter can work on a variety of different liquid types. The common measured liquids are water, sea water, kerosene, petrol, fuel oil, crude oil, glycol/water, chilled water, river water, potable water, agricultural irrigation water, etc. There is an option to input c...Read more -
Doppler Flow Meter DF6100
DF6100 series Doppler Flow Meter is a wall mounted or portable clamp on doppler flow meter ( except insertion type ) which clamps to the outside of the measured pipe to gain water flow measurement in full filled pipe. The ultrasonic Doppler technology used by Lanry Doppler non contact type flow m...Read more -
Open channel flow meter DOF6000
It also named area velocity flow meter or doppler flow meter. The Lanry area velocity doppler flowmeter uses a submersible ultrasonic doppler sensor to measure both the level and velocity of water flow to calculate flow in an open channel or pipe, the pipe could be full water or not. Lanry Area v...Read more -
What is the Scale Factor function ?
This function can be used to make the Doppler flow meter system agree with a different or reference flow meter, or to compensate for an installation where there is inadequate straight pipe to obtain a laminar flow profile, by applying a correction factor/multiplier to the readings and outputs. Th...Read more -
What are the common questions of ultrasonic flowmeter ?
1. The measurement of flow rate shows abnormal and huge data drastic change. Reason: Maybe Ultrasonic transducers are installed in the pipeline with big vibration or in the regulator valve, pump, downstream of the shrinkage hole; How to deal with：Installing the sensor should be far away from vi...Read more -
Transit-Time ultrasonic flowmeter portable, handheld and fixed between the advantages and disadva...
1) Measurement characteristics: portable and handheld flowmeter’s measurement performance is better. This is because portable and handheld flow meters use battery power supply, and stationary or wall mounted flow meter’s power supply use AC or DC power supply, even if the use of DC po...Read more -
How to install Lanry DF6100 series Doppler flow transducers ?
The premise of DF6100 series doppler flow meter’s work is the measured pipe must be full of liquids. In theory, doppler sensors need to be located the reference mounting positions of 3 and 9 o’clock. Two transducers called A and B transducer, A is transmitting transducer and B is receiving transd...Read more -
Why does transit time insertion sensors adopt Z method instead of V method?
There are four ways to install transit time ultrasonic sensors, V method and Z method are commonly used, and Z method is used to install transit time insertion sensors on site. This is mainly due to the insertion type sensors installation characteristics and Z method signal transmission mode. Whe...Read more -
Why should ultrasonic flowmeter sensors not be installed at the top or bottom of the pipe as much...
When measuring the flow of liquid, because the liquid contains a certain volume of gas, when the fluid pressure is lower than the saturated vapor pressure of the liquid, the gas will be released from the liquid to form bubbles accumulated in the upper part of the pipeline, the bubble has a great ...Read more -
What pipes and what medium Lanry brand insertion ultrasonic flow meter can measure ?
In general, insertion ultrasonic flow-meter doesn’t have special requirements for measured pipes. For weldable metal pipelines, insertion sensors can be weld directly into the pipe. For non-weldable pipework, it needs to be installed by hoop. What medium can be measured for Lanry brand ...Read more -
What are the common installation methods of transit time ultrasonic flow-meters transducers ?
For clamp on transit time ultrasonic flow-meter, V and Z method are recommended. Theoretically, when the pipe diameter is from 50mm to 200mm, We usually recommend you to use V method to install it. As for other pipe diameters, we suggest you use Z method to install it. If there exists some reas...Read more
