Understanding The Application Of Daniel Orifice Plate

The sizing of Daniel orifice plate is normally done with software provided by manufacturers of the device. The orifice plate meter provides a restriction to the flow and create the necessary differential pressure. Well, it is one of the most popular and versatile flowmeter on the market.

The sizing of Daniel orifice plate holder consists of three elements – a primary element to create the DP signal, a transmitter to measure the DP and convert it to the electronic and digital signal. The tertiary elements calculate the displays, stores and transmits the corrected flow rate on the basis of measured values.

Choosing The Right Specification

Any successful orifice meter deployment is based on establishing the right specification and ensure that the orifice plate meter is sized correctly. For custody transfer application it is required to have a list of specifications.

Variables like liquid and gas amounts also need to be considered with orifice meter accuracy maintained in liquid stream to contain up to 5.5 percent by volume of gas and up to 2.2 percent by weight of liquids in gas.

Choose The Right Orifice Holding Tool

Another crucial question at the outset would be choice of orifice holding device. Proper fitting is very crucial for the accuracy and performance as it required for flexibility while removing and replacing plates.

Dual chamber orifice fitting is another option that allows the removal of the plate under flowing conditions. The dual chamber is separated by a slide valve with a gear shaft. Once the slide valve is closed and the pressure is bled from the top chamber – the orifice plate can be removed safely.

In addition, there are multi-hole orifice plate to combine the technologies of orifice plate and flow conditioner for making a measurement device with short upstream piping installation requirements. Such device comes with traditional single-hole orifice plate deign however have several bores to distribute the flow through smaller bores rather the single large bore.

The Importance of Maintenance

Frequent inspection and maintenance of the meter should be conducted for reducing lost and unaccounted for corresponding liquid. Monthly operation of the fitting is also recommended that includes opening, closing and lubricating the slide valve for rotating the gear shafts and cleaning the drain plug holes. These steps should be performed once the senior fitting has been depressurized and the line has been blown down.

Everything You Should Know About Turbine Flow Meter

Image
Daniel Turbine Meter is used for volumetric total flow and flow rate measurement. The mechanism has a relatively simple working principle. Since fluid flows through the turbine meter – it affects the turbine blades that are free to rate about an axis along the center line of the housing. Liquid turbine serves a variety of hydrocarbon application including fiscal and custody transfer, check metering or blending. Well, the flow meters are installed for measurement during crude oil production, storage inventory control, floating production, offloading also refined product loading and offloading. The repeatability of the meter ensures quality measurement over a wide range of flow rates, temperature, composition, and viscosities. It is the largest combination of line sizes, pressure and materials as standard turbine meter configuration with the most international product approval. Daniel PT Turbine Meter It is widely preferred for their low-cost installation, maintenance ownership. D...

Accurate Liquid Turbine Flow Meters for Oil and Gas Applications

Image
Chemical blending, custody transfer, and petroleum processing are just a few of the applications where precise liquid flow measurement is essential. To guarantee accurate and trustworthy measurements, high-accuracy liquid turbine flow meters are needed. Since it is so accurate and dependable, the liquid turbine meter has become very popular. This blog will go into greater detail about the Daniel 1500 Turbine meter . Knowing How Turbine Meters Work The purpose of a turbine meter is to gauge the volumetric flow rate of liquids moving through a pipeline. The force of the flowing liquid rotates a turbine rotor that is placed inside the flow stream. The electrical pickoffs on the meter body then transform the rotating speed of the liquid as it passes through the turbine meter into electrical signals. Accurate measurement is possible because the electrical frequency output is proportionate to the flow rate, with each pulse denoting a tiny incremental volume of flow. Turbine Meter C...

How Can Excel Loading System Help You

Image
Excel Loading Systems may assist in the safe and effective transportation of gases and liquids, especially bulk goods, from totes, railcars, and vehicles. These systems include advantages such as quicker loading and unloading times, enhanced efficiency, decreased environmental impact, and higher safety. HERE'S A CLOSER LOOK AT THE WAYS EXCEL LOADING SYSTEMS MIGHT BE BENEFICIAL: Enhanced Security Loading Arms at the Bottom - Minimizes the chance of falls and injuries by enabling operators to stay on the ground. Loading a Closed System - Reduces the chance of coming into contact with dangerous substances by minimizing vapor discharges. Loading Arms that are Properly Built and Maintained - Minimize the impact on the environment by lowering the possibility of spills and leaks during transport. Enhanced Productivity In order to increase throughput, loading arms enable the loading of numerous compartments in a truck or train at the same time. Reduced downtime and increased operationa...
