Coriolis Mass Flowmeter

Coriolis mass flowmeter is developed according to the principle of coriolis mass flow meter, it can be directly measure parameters such as mass flow , density and temperature. It has been widely used in petroleum, natural gas, chemical, pipeline transportation industries. Its function is for trade settlement and process control to ensure precision reflection, enhanced safety and maintenance cost save.

AMF series Coriolis meter's mass flow can yield up to 0.15% accuracy. It is incredibly accurate and excellent repetition. And allows you as producer to make consistency and repeatability of batches.

Direct mass flow. Do not lose the accuracy by measurement of T, P, Z &ρand Volume conversion.

It can measure more than one variate in the tube. Such as mass flow, volume flow, density, concentration, temperature and viscosity.

It's lower maintenance. There is no moving parts in Coriolis meter and no impellers and obstructions in the line. So, There is no movement and wearing mar. The meter's last forever.

Measure high viscosity and non- Newtonian fluid, besides homogeneous fluid, not only single phase fluid can be measured, but also homogeneous multi- phase fluid.

Good antiseptic property, various common corrosion fluids can be measured.

Flow Meter air

Water flow meter atau liquid flow meter atau Flow meter air ada beberapa type yang bisa digunakan disesuaikan dengan jenis fluid yang mengalir dan fungsi flow meter air sendiri. Yang dimaksud dengan flow meter air atau water flow meter atau water meter adalah jenis liquid yang mana basenya adalah water.

 

Pada dunia industri manufacture, oil and gas, pertambangan, perhotelan, rumah sakit dan lainnya water flow meter atau flow meter air atau liquid flow meter ini dapat dikelompokan pada jenis liquid air dan prosesnya  :

- Flow meter limbah
- Chemical flow meter
- Flow meter air bersih
- Flow meter air murni ( demin water )
- Raw water Flow Meter
- dan lainnya

Ada beberapa jenis flow meter yang aplikasinya cocok digunakan pada jenis fluid diatas dimana tetap mengacu pada cara kerja flow meter dan juga pada aplikasi yang diinginkan oleh para pemakai flow meter. Untuk Flow meter yang sering digunakan adalah : 

- Flow meter electromagnetic / Mag Flow Meter

- Turbine Flow meter
- Ultrasonic flow meter
- Woltman Flow Meter
-  Paddle wheel Flow meter
- Vortex flow meters
- Variable Area Flow Meters

Untuk jenis Fluid yang basenya water yang mengandung kotoran baik itu kotoran limbah maupun karena raw waternya seperti air dari sungai karena adanya kotoran sampah atau pasir, mungkin jenis flow meter yang cocok adalah Jenis Flow meter yang tidak mempunyai komponen yang bergerak dalam sensornya atau bisa juga untuk jenis flow meter yang tidak mempunyai contact langsung dengan liquid. Dimana untuk kedua jenis flow meter ini karena sifat dan cara kerja flow meter membuat karakteristik sensornya akan lebih awet dan akurasinya lebih terjamin karena tidak terpengaruh adanya kotoran-kotoran dalam fluid. Namun demikian karena sifat dan karakteristik kerja flow meter ini menuntut adanya kesempurnaan aliran, seperti tidak boleh adanya rongga-rongga udara karena akan dibaca sebagai aliran palsu ,yang menyebabkan sensor tidak mampu membaca dengan baik, kecuali jenis dopler ultrasonic yang harganya sangat mahal. dan untuk electromagnetic flow meter cukup banyak disukai karena akurasinya cukup memadai dan harganya juga tidak mahal walaupun ada kelemahan disebabkan jika aliran fluida terjadi turbulen. Namun demikian untuk mengatasi turbulen pada jenis electromagnetic flow meter bisa juga aplikasinya dengan menggunakan air drain ( pembuangan udara ) yang bisa dipasang setelah electromagnetic flow meter.

Sedangkan untuk fluida dengan base water namun mempunyai PH atau tingkat keasaman atau kebasan terlalu ekstrim, selain digunakan ultrasonic ( non contac ) bisa juga digunakan electromagnetic dengan bahan non metal (  Plastic atau PVC) atau jika fluid tersebut bersih bisa juga digunakan jenis flow meter turbine dengan bahan dari PVC atau mungkin bisa digunakan matrial stainless steel 316L. Dengan karakteristic elecromagnetic flow meter yang tidak mempunyai bagian/part yang bergerak dalam tabung flow meter, type electromagnetic flow meter ini cocok sekali jika dipakai untuk fluida / cairan yang tidak bersih / kotor, baik itu karena adanya kotoran berupa serat, getah, pasir ataupun rumput dan kotoran lainnya sepanjang cairan tersebut mengandung conductivity yang di persyaratkan.

Pada dasarnya hampir semua jenis flow meter dapat digunakan untuk aplikasi flow meter yang menggunakan dasar air. Namun demikian pemilihan jenis flow meter tetap di pertimbangkan agar kita bisa mendapatkan jenis flow meter yang sesuai dengan aplikasi yang kita perlukan dengan pertimbangan kecocokan akurasi dan biaya yang di keluarkan baik biaya maintenance maupun harga flow meter nya itu sendiri. Jenis flow meter atau type flow meter yang sering digunakan dalam dunia industri untuk flow meter dengan liquid air adalah :
- Turbine flow meter
- Magnetic Flow meter
- Ultrasonic Flow meter
- Vortex Flow meter
- DP Flow Flow meter
- Woltman type water meter 

EX100/200 Insert Electromagnetic Flow Meter

Fixed depth electromagnetic insertion flow meters 
Seametrics Insertion Flow Meter
Electromagnetic Insertion Flow Meter

GENERAL INFORMATION

The complete lack of moving parts of the EX100/200 Series seametrics insertion flow sensor is the source of its reliability. Brass and stainless steel models withstand a variety of temperature, pressure, and chemical conditions. The EX-Series has no rotor to stop turning in dirty water and there are no bearings to wear out. Like all magmeters, when used in chemical injection applications, these meters should be installed upstream of the chemical line (or far enough downstream to allow complete mixing of fluids before the meter).

A rapidly reversing magnetic field is produced in the lower housing. As the fluid moves through this field, a voltage is generated that is measured and translated into a frequency signal proportional to flow rate. This square wave signal can be sent directly to a PLC or other control or can be converted using any of the Seametrics family of indicators and converters.

A modular system of electronics can be attached directly to the flow sensor or remotely mounted. The Seametrics FT420 provides full indication of rate and total, plus 4-20 mA output. The AO55 provides blind 4-20 mA output, and the DL76 is a battery-powered data logger.

Features :

• Depth adjustable sensors
• EX101 fits any 1-1/2" pipe fitting (standard saddle, for instance) and adjusts to pipe sizes 3-10"
• EX201 adjusts to pipe sizes 10-48"
• Meter extends only about 1/8 of pipe diameter, minimizing potential for clogging with debris
• Accept SeaMetrics modules for rate and total indication, 4-20 mA conversion, data logging, and flow switching
• Alternatively, signal can be sent directly to a PLC or other control
• Available in brass or 316 stainless steel
• Immersibility and reverse flow output available

The adapter fitting of the EX sensor is standard male NPT, and can be directly threaded into ordinary saddles or threaded weld fittings. The EX115 and 215 include an isolation valve, allowing hot-tap installation, or installation and removal under pressure; a bronze ball valve is standard, with a 316 stainless steel valve option if needed. Reverse flow output and immersibility are optional.
