To ensure correct dosing, level or volume is measured. Unfortunately, a batch of vessels were damaged and dented accidentally during the long distance transportation, and can’t be well recovered by the side in a short time. They are asking us how they can measure the correct quantity (mass or volume) of the liquid, since the height measurement will be wrong? They would l...

With the wide application of information communication technology and sensing technology in the field of agricultural production, the agricultural irrigation has been developed. Using wireless pressure sensor and automatic data monitoring technology, we can realize real-time monitoring of water consumption and irrigation in agriculture, and then realize dynamic control a...

Following we will discuss what specific solids ultrasonic level sensors can measure. No.1, Powdered solids Generally ultrasonic level sensors are NOT recommended to measure powdered solids such as foam particles, flour, soybean powder, dust, cement, fly ash, wood residue. As you may know that when an ultrasonic level sensor with a range of 10 meters measures flour, onl...

It's better have wireless data transmission for remote data view, and low operation cost in the later stage. Holykell recommends Radar Flow Meter HRF600 for them. Related Product HRF600 radar flow meter is a fully automatic radar flow meter based on microwave technology. The product comes with a flow sensor and a water level sensor. With advanced K-band planar radar t...

Volumetric flow meters are designed to calculate volume, or the amount of fluid passing through the system during a given time period. They have various types, and positive displacement flow meter is a typical one. What Is A Positive Displacement Flow Meter? A positive displacement type flow meter as a mechanical flow meter is a common type of Volumetric Flow Meter. It...

This can be done using a level measurement sensor. Holykell provides various level sensors for different applications. And today we are going to talk about two main level sensors, ultrasonic level sensors and radar level sensors. And how to select between the two. Holykell ultrasonic level sensors use a non-contact level measurement technique. We are providing split typ...

We specialize in the R&D and production of magnetic flow meters. Various types and sizes are provided and they are widely used in petroleum, chemical, metallurgical, water supply and water ...

We should pay attention to the installation since if the installation is unreasonable, it will greatly impact the accuracy and the service life of the instrument. To measure natural gas, one of the most commonly device is a vortex flow meter. Following we will briefly introduce the installation notices. Installation of Natural Gas Flow Meter 1. The natural gas flow met...

It provides continuous pressure monitoring and control. Most of the important work involves hydraulics, and Holykell HPT906 pressure sensor is designed and came into being based on it. It plays a critical role in hydraulic applications and covers pressures range up to 2000 bar (29007psi). Since the safety comes first for hydraulic applications, its structure and materia...

Here is the installation method for submersible borehole level sensors. 1. Installation method for still wells or tanks: ①When it is installed in a static deep well or tank, a steel pipe is usually fixed in the water, and then put the level sensor into the metal pipe. ②Fix the sensor to the metal tube. ③Suspension method: Install through the cable hanger 2. Installat...

For example, HVAC pressure transducer is an integral part of the monitoring method that measures how air compressors are running at all times. There are a few challenges though. On one hand, compressed air can be fatal, in some cases it may leak or even explode. One the other hand, the increasing energy prices have pushed factories and buildings to run the systems at an ...
